    Security fixes in Vaadin Framework 7.1.11

    - -

    - Vaadin 7.1.11 fixes two security issues discovered during internal review. -

    -

    Escaping of OptionGroup item icon URLs

    -

    - The issue affects OptionGroup with item icons. Proper escaping of the - src-attribute on the client side was not ensured when using icons for - OptionGroup items. This could potentially, in certain situations, allow - a malicious user to inject content, such as javascript, in order to - perform a cross-site scripting (XSS) attack. -

    -

    - In order for an application to be vulnerable, user provided input must - be used to form a URL used to display an icon for an OptionGroup item, - when showing that Option Group to other users.
    - The vulnerability has been classified as moderate, due to it's limited - application. -

    -

    Escaping of URLs in Util.getAbsoluteUrl()

    -

    - The client side Util.getAbsoluteUrl() did not ensure proper escaping - of the given URL. This could potentially, in certain situations, allow - a malicious user to inject content, such as javascript, in order to - perform a cross-site scripting (XSS) attack. -

    -

    - The method is used internally by the framework in such a manner that it - is unlikely this attack vector can be utilized in practice. However, - third party components, or future use of the method, could make an - attack viable.
    - The vulnerability has been classified as moderate, due to it's limited - application. -

This new approach makes it possible to have rows cached even if they are not in view. It also improves performance since there's no need to do an RPC every time scrolling changes what is visible.

From 6653224d8defe79ecb8749eab96adccd626c76bf Mon Sep 17 00:00:00 2001
From: Henrik Paul 
Date: Mon, 30 Jun 2014 18:18:32 +0300
Subject: Adds the ability to swap between the three client side selection
 models (#13334)

So, this means when the selection model is modified on the server side,
the client side changes accordingly.

Change-Id: I3c7e3802cecdf9dfd64f5296c48fca5dfc58787d

Subject: Generate type data for AbstractRendererConnector.createRenderer
 (#13334)

The declared return type of the most-derived getRenderer method is stored
to make the default createRenderer implementation work. This is identical
to the way AbstractComponentConnector getWidget and createWidget work.

From: Johannes Dahlström

Subject: Start rewrite of client-side Grid header/footer API (#13334)

The old API is marked as deprecated and does not work anymore.

Currently supported:
* A single hard-coded header
* Text captions

TODO:
* Footers
* 0..n headers and footers
* Column spanning
* HTML content
* Widget content
* Component content
* Sorting/Indicators
* Server side API
* Shared state handling

Change-Id: I0448c36c8406807037b5e21e2db205a2ee24bc8a

Subject: Client-side Grid header/footer rewrite: add add/remove rows support
 (#13334)

Currently supported:
* Adding and removal of header and footer rows
* Header is single-row by default
* Footer is zero-row by default
* Text captions

TODO:
* Column spanning
* HTML content
* Widget content
* Component content
* Sorting/Indicators
* Server side API
* Shared state handling

Subject: Client-side Grid header/footer rewrite: add section setVisible
 (#13334)

Currently supported:
* Adding and removal of header and footer rows
* Header is single-row by default
* Footer is zero-row by default
* Text captions
* Showing and hiding the whole header or footer

TODO:
* Column spanning
* HTML content
* Widget content
* Component content
* Sorting/Indicators
* Server side API
* Shared state handling

Subject: Grid header/footer rewrite: add partial shared state support (#13334)

Currently supported:
* Adding and removal of header and footer rows
* Header is single-row by default
* Footer is zero-row by default
* Text captions
* Showing and hiding the whole header or footer
* Passing captions and visibility in shared state

TODO:
* Column spanning
* HTML content
* Widget content
* Component content
* Sorting/Indicators
* Server side API
* Rest of shared state handling

Subject: Client-side Grid header/footer rewrite: add default header support
 (#13334)

Currently supported:
* Adding and removal of header and footer rows
* Header is single-row by default
* Footer is zero-row by default
* Text captions
* Showing and hiding the whole header or footer
* Default header rows for sorting UI

TODO:
* Column spanning
* HTML content
* Widget content
* Component content
* Server side API
* Shared state handling

Change-Id: I3d6a2b75fad87780f83238ab792bbbcfe99a48fd

From 64caee7afa90ac8b16ba48e768204aa36248ecbe Mon Sep 17 00:00:00 2001
From: John Ahlroos 
Date: Mon, 28 Jul 2014 16:26:01 +0300
Subject: Allow merging header and footer cells again #13334

This changeset adds the possibility to merge header and footer cells by
using HeaderRow.join().

Note: Currently this does not support hidden columns, support for it
should be added in a later changeset.

Change-Id: I42e089ef2ac6eea304e355423b274159a79baa89

Subject: Removed ColumnGroup implementation from client side Grid #13334

The ColumnGroup concept was depracated in favour of directly
manipulating the header/footer cell colspans. This changeset removes the
old dead code no longer in use.

 /**
- * Data grid component
+ * A grid component for displaying tabular data.
+ * 
    
+ * Grid is always bound to a {@link Container.Indexed}, but is not a
+ * {@code Container} of any kind in of itself. The contents of the given
+ * Container is displayed with the help of {@link Renderer Renderers}.
  * 
- * 
    Lazy loading
     TODO To be revised when the data data source
- * implementation has been don.
+ * 
    Headers and Footers
    
+ * 
    
  * 
- * 
    Columns
     The grid columns are based on the property ids of the
- * underlying data source. Each property id represents one column in the grid.
- * To retrive a column in the grid you can use {@link Grid#getColumn(Object)}
- * with the property id of the column. A grid column contains properties like
- * the width, the footer and header captions of the column.
  * 
- * 
    Auxiliary headers and footers
     TODO To be revised when column
- * grouping is implemented.
+ * 
    Converters and Renderers
    
+ * 
    
+ * Each column has its own {@link Renderer} that displays data into something
+ * that can be displayed in the browser. That data is first converted with a
+ * {@link com.vaadin.data.util.converter.Converter Converter} into something
+ * that the Renderer can process. This can also be an implicit step - if a
+ * column has a simple data type, like a String, no explicit assignment is
+ * needed.
+ * 
    
+ * Usually a renderer takes some kind of object, and converts it into a
+ * HTML-formatted string.
+ * 
    
+ * 
    + * Grid grid = new Grid(myContainer);
+ * GridColumn column = grid.getColumn(STRING_DATE_PROPERTY);
+ * column.setConverter(new StringToDateConverter());
+ * column.setRenderer(new MyColorfulDateRenderer());
+ * 
    
+ * 
+ * 
    Lazy Loading
    
+ * 
    
+ * The data is accessed as it is needed by Grid and not any sooner. In other
+ * words, if the given Container is huge, but only the first few rows are
+ * displayed to the user, only those (and a few more, for caching purposes) are
+ * accessed.
+ * 
+ * 
    Selection Modes and Models
    
+ * 
    
+ * Grid supports three selection {@link SelectionMode modes} (single,
+ * multi, none), and comes bundled with one
+ * {@link SelectionModel model} for each of the modes. The distinction
+ * between a selection mode and selection model is as follows: a mode
+ * essentially says whether you can have one, many or no rows selected. The
+ * model, however, has the behavioral details of each. A single selection model
+ * may require that the user deselects one row before selecting another one. A
+ * variant of a multiselect might have a configurable maximum of rows that may
+ * be selected. And so on.
+ * 
    
+ * 
    + * Grid grid = new Grid(myContainer);
+ * 
+ * // uses the bundled SingleSelectionModel class
+ * grid.setSelectionMode(SelectionMode.SINGLE);
+ * 
+ * // changes the behavior to a custom selection model
+ * grid.setSelectionModel(new MyTwoSelectionModel());
+ *

From: Johannes Dahlström 
Date: Tue, 19 Aug 2014 16:23:04 +0300
Subject: Initial client-side editor row implementation (#13334)

Only shows a bare grey row for now. Enter opens editor for
active row, Esc hides editor.

TODO

* Double-click to edit does not work
* Scrolling to edit hidden row does not work
* EditorRowHandler to bind data+widgets
* Server-side integration
* Commit/discard buttons

Subject: Pass editor row enabled state in shared state (#13334)

Also refactor editor row tests a bit. Include separate GWT and Vaadin
test cases at least until communication is finished.

From 8dfbccb322aea14863ab8b54b5bc268296b86fb5 Mon Sep 17 00:00:00 2001
From: Johannes Dahlström

Subject: Implement data binding and edit cancel mechanism for editor row
 (#13334)

This patch contains only the generic parts and a test EditorRowHandler.
The Vaadin-specific implementation will be submitted as a separate change.

Subject: Reworks the datasource size logic (#13334)

There's no setting of size, but it's inferred instead. Also, you can't
set the size, only ask for a size.

Subject: Ensure Renderers that do type conversions work properly (#13334)

Before this change eg. DateRenderer would end up calling JsonCodec.encode
with mismatching arguments. This "just happened to work" but does not work
in all cases.

+                 * 1) Grid is scrolled somewhere in the middle and all the
+                 * rows-inview are removed. We need a new pageful.
+                 * 
+                 * 2) Grid is scrolled somewhere in the middle and none of the
+                 * visible rows are removed. We need no new rows.
+                 * 
+                 * 3) Grid is scrolled all the way to the bottom, and the last
+                 * rows are being removed. Grid needs to scroll up and request
+                 * for more rows at the top.
+                 * 
+                 * 4) Grid is scrolled pretty much to the bottom, and the last
+                 * rows are being removed. Grid needs to be aware that some
+                 * scrolling is needed, but not to compensate for all the
+                 * removed rows. And it also needs to request for some more rows
+                 * to the top.
+                 * 
+                 * 5) Some ranges of rows are removed from view. We need to
+                 * collapse the gaps with existing rows and load the missing
+                 * rows.
+                 * 
+                 * 6) The ultimate use case! Grid has 1.5 pages of rows and
+                 * scrolled a bit down. One page of rows is removed. We need to
+                 * make sure that new rows are loaded, but not all old slots are
+                 * occupied, since the page can't be filled with new row data.
+                 * It also needs to be scrolled to the top.
+                 * 
+                 * So, it's easier (and safer) to do the simple thing instead of
+                 * taking all the corner cases into account.

Subject: Restructures Escalator method hierarchy (#13334)

Previously AbstractRowContainer.paintInsertRows was simply overridden by
BodyRowContainer, which was hard to follow. Now ARC.pIR is an abstract method
and the implementation has been put into another protected method.

Subject: Fix RpcDataSource to use RPC for row pins/unpins (#13334)

This patch removes the temprarilyPinnedRows workaround from
AbstractRemoteDataSource and refactors the whole feature to be part of
RpcDataSource where it should be.

Subject: Renames "active cell" to "cell focus" or "focused cell" (#13334)

It was quite confusing to have so many meanings of "active".
Active row still means "the visible rows". And onActivate still means
enter or click on a cell.

+/**
+ * A grid component for displaying tabular data.
+ * 
    
+ * Grid is always bound to a {@link Container.Indexed}, but is not a
+ * {@code Container} of any kind in of itself. The contents of the given
+ * Container is displayed with the help of {@link Renderer Renderers}.
+ * 
+ * 
    Headers and Footers
    
+ * 
    
+ * 
+ * 
+ * 
    Converters and Renderers
    
+ * 
    
+ * Each column has its own {@link Renderer} that displays data into something
+ * that can be displayed in the browser. That data is first converted with a
+ * {@link com.vaadin.data.util.converter.Converter Converter} into something
+ * that the Renderer can process. This can also be an implicit step - if a
+ * column has a simple data type, like a String, no explicit assignment is
+ * needed.
+ * 
    
+ * Usually a renderer takes some kind of object, and converts it into a
+ * HTML-formatted string.
+ * 
    
+ * 
    + * Grid grid = new Grid(myContainer);
+ * GridColumn column = grid.getColumn(STRING_DATE_PROPERTY);
+ * column.setConverter(new StringToDateConverter());
+ * column.setRenderer(new MyColorfulDateRenderer());
+ * 
    
+ * 
+ * 
    Lazy Loading
    
+ * 
    
+ * The data is accessed as it is needed by Grid and not any sooner. In other
+ * words, if the given Container is huge, but only the first few rows are
+ * displayed to the user, only those (and a few more, for caching purposes) are
+ * accessed.
+ * 
+ * 
    Selection Modes and Models
    
+ * 
    
+ * Grid supports three selection {@link SelectionMode modes} (single,
+ * multi, none), and comes bundled with one
+ * {@link SelectionModel model} for each of the modes. The distinction
+ * between a selection mode and selection model is as follows: a mode
+ * essentially says whether you can have one, many or no rows selected. The
+ * model, however, has the behavioral details of each. A single selection model
+ * may require that the user deselects one row before selecting another one. A
+ * variant of a multiselect might have a configurable maximum of rows that may
+ * be selected. And so on.
+ * 
    
+ * 
    + * Grid grid = new Grid(myContainer);
+ * 
+ * // uses the bundled SingleSelectionModel class
+ * grid.setSelectionMode(SelectionMode.SINGLE);
+ * 
+ * // changes the behavior to a custom selection model
+ * grid.setSelectionModel(new MyTwoSelectionModel());
+ * 
    
+ *

-/**
- * A grid component for displaying tabular data.
- * 
    
- * Grid is always bound to a {@link Container.Indexed}, but is not a
- * {@code Container} of any kind in of itself. The contents of the given
- * Container is displayed with the help of {@link Renderer Renderers}.
- * 
- * 
    Headers and Footers
    
- * 
    
- * 
- * 
- * 
    Converters and Renderers
    
- * 
    
- * Each column has its own {@link Renderer} that displays data into something
- * that can be displayed in the browser. That data is first converted with a
- * {@link com.vaadin.data.util.converter.Converter Converter} into something
- * that the Renderer can process. This can also be an implicit step - if a
- * column has a simple data type, like a String, no explicit assignment is
- * needed.
- * 
    
- * Usually a renderer takes some kind of object, and converts it into a
- * HTML-formatted string.
- * 
    
- * 
    - * Grid grid = new Grid(myContainer);
- * GridColumn column = grid.getColumn(STRING_DATE_PROPERTY);
- * column.setConverter(new StringToDateConverter());
- * column.setRenderer(new MyColorfulDateRenderer());
- * 
    
- * 
- * 
    Lazy Loading
    
- * 
    
- * The data is accessed as it is needed by Grid and not any sooner. In other
- * words, if the given Container is huge, but only the first few rows are
- * displayed to the user, only those (and a few more, for caching purposes) are
- * accessed.
- * 
- * 
    Selection Modes and Models
    
- * 
    
- * Grid supports three selection {@link SelectionMode modes} (single,
- * multi, none), and comes bundled with one
- * {@link SelectionModel model} for each of the modes. The distinction
- * between a selection mode and selection model is as follows: a mode
- * essentially says whether you can have one, many or no rows selected. The
- * model, however, has the behavioral details of each. A single selection model
- * may require that the user deselects one row before selecting another one. A
- * variant of a multiselect might have a configurable maximum of rows that may
- * be selected. And so on.
- * 
    
- * 
    - * Grid grid = new Grid(myContainer);
- * 
- * // uses the bundled SingleSelectionModel class
- * grid.setSelectionMode(SelectionMode.SINGLE);
- * 
- * // changes the behavior to a custom selection model
- * grid.setSelectionModel(new MyTwoSelectionModel());
- *

Subject: Hardens the logic in Escalator scrolling (#13334)

Filtering a Grid broke Escalator's scrolling. This probably has to do
with several row-modifications combined with scrolling and adjustments.
The previous method had the possibility for ridiculous adjustments,
going out of bounds. This makes the changes absolute rather than
relative.

though there were no additional selection events.

Subject: Flattening server-side EditorRow API (#13334)

This commit just flattens the EditorRow class into Grid without changing
any behavior. isEditing() was changed to isEditorRowActive() since
isEditorRowEditing() didn't make any sense. Some javadocs have also been
slightly tweaked.

Subject: Remove selection column from single selection model (#13334)

This patch makes some changes to selection model logic and refactors the
space selection handling from MultiSelectionRenderer to its own class.

Subject: Split and capitalize header captions by default

Only done on the server side where we have property ids to generate the default
headers from. On the client side you must always specify the header.

From e1e960f62269d09b813908bcab87be3028b15397 Mon Sep 17 00:00:00 2001
From: Leif Åstrand 
Date: Thu, 11 Dec 2014 19:18:44 +0200
Subject: Make AbstractRemoteDataSource easier to use (#13334)

- Adds a callback to requestRows so implementors know what to do when
receiving data
- Guestimate the initial amount of available rows so an initial request
can be made before the actual size is known

From: Artur Signell

Subject: Do not prefix generated styles (#13334)

Unprefixed styles are easier to use, are consistent with header styles and
multiple styles are consistent instead of the first one being prefixed.

Subject: Refactor server-side editor row to work in real(er) cases (#13334)

- Don't configure fields for properties without columns
- Rename "bind" to "set" to match the getter
- Make it possible to get a field before editing has started
- Remove setting of editable since the field can be configured directly
- Remove error handler concept since we have not tests and no use cases
- Unbind and detach field when removing a column

- Maintenance Notes! Reading these might save your day.
- (note for editors: line width is 80 chars, including the
- one-space indentation)
-
-
- == Row Container Structure
-
- AbstractRowContainer
- |-- AbstractStaticRowContainer
- | |-- HeaderRowContainer
- | `-- FooterContainer
- `---- BodyRowContainer
-
- AbstractRowContainer is intended to contain all common logic
- between RowContainers. It manages the bookkeeping of row
- count, makes sure that all individual cells are rendered
- the same way, and so on.
-
- AbstractStaticRowContainer has some special logic that is
- required by all RowContainers that don't scroll (hence the
- word "static"). HeaderRowContainer and FooterRowContainer
- are pretty thin special cases of a StaticRowContainer
- (mostly relating to positioning of the root element).
-
- BodyRowContainer could also be split into an additional
- "AbstractScrollingRowContainer", but I felt that no more
- inner classes were needed. So it contains both logic
- required for making things scroll about, and equivalent
- special cases for layouting, as are found in
- Header/FooterRowContainers.
-
-
- == The Three Indices
-
- Each RowContainer can be thought to have three levels of
- indices for any given displayed row (but the distinction
- matters primarily for the BodyRowContainer, because of the
- way it scrolls through data):
-
- - Logical index
- - Physical (or DOM) index
- - Visual index
-
- LOGICAL INDEX is the index that is linked to the data
- source. If you want your data source to represent a SQL
- database with 10 000 rows, the 7 000:th row in the SQL has a
- logical index of 6 999, since the index is 0-based (unless
- that data source does some funky logic).
-
- PHYSICAL INDEX is the index for a row that you see in a
- browser's DOM inspector. If your row is the second 
- element within a  tag, it has a physical index of 1
- (because of 0-based indices). In Header and
- FooterRowContainers, you are safe to assume that the logical
- index is the same as the physical index. But because the
- BodyRowContainer never displays large data sources entirely
- in the DOM, a physical index usually has no apparent direct
- relationship with its logical index.
-
- VISUAL INDEX is the index relating to the order that you
- see a row in, in the browser, as it is rendered. The
- topmost row is 0, the second is 1, and so on. The visual
- index is similar to the physical index in the sense that
- Header and FooterRowContainers can assume a 1:1
- relationship between visual index and logical index. And
- again, BodyRowContainer has no such relationship. The
- body's visual index has additionally no apparent
- relationship with its physical index. Because the  tags
- are reused in the body and visually repositioned with CSS
- as the user scrolls, the relationship between physical
- index and visual index is quickly broken. You can get an
- element's visual index via the field
- BodyRowContainer.visualRowOrder.
-
- Currently, the physical and visual indices are kept in sync
- _most of the time_ by a deferred rearrangement of rows.
- They become desynced when scrolling. This is to help screen
- readers to read the contents from the DOM in a natural
- order. See BodyRowContainer.DeferredDomSorter for more
- about that.

-/**
- * A data grid view that supports columns and lazy loading of data rows from a
- * data source.
- * 
- * 
    Columns
    
- * 
    
- * Each column in Grid is represented by a {@link GridColumn}. Each
- * {@code GridColumn} has a custom implementation for
- * {@link GridColumn#getValue(Object)} that gets the row object as an argument,
- * and returns the value for that particular column, extracted from the row
- * object.
- * 
    
- * Each column also has a Renderer. Its function is to take the value that is
- * given by the {@code GridColumn} and display it to the user. A simple column
- * might have a {@link com.vaadin.client.ui.grid.renderers.TextRenderer
- * TextRenderer} that simply takes in a {@code String} and displays it as the
- * cell's content. A more complex renderer might be
- * {@link com.vaadin.client.ui.grid.renderers.ProgressBarRenderer
- * ProgressBarRenderer} that takes in a floating point number, and displays a
- * progress bar instead, based on the given number.
- * 
    
- * See: {@link #addColumn(GridColumn)},
- * {@link #addColumn(GridColumn, int)} and {@link #addColumns(GridColumn...)}.
- * Also {@link GridColumn#setRenderer(Renderer)}.
- * 
- * 
    Data Sources
    
- * 
    
- * Grid gets its data from a {@link DataSource}, providing row objects to Grid
- * from a user-defined endpoint. It can be either a local in-memory data source
- * (e.g. {@link com.vaadin.client.ui.grid.datasources.ListDataSource
- * ListDataSource}) or even a remote one, retrieving data from e.g. a REST API
- * (see {@link com.vaadin.client.data.AbstractRemoteDataSource
- * AbstractRemoteDataSource}).
- * 
- * 
- * @param 
- *            The row type of the grid. The row type is the POJO type from where
- *            the data is retrieved into the column cells.

+ Maintenance Notes! Reading these might save your day.
+ (note for editors: line width is 80 chars, including the
+ one-space indentation)
+
+
+ == Row Container Structure
+
+ AbstractRowContainer
+ |-- AbstractStaticRowContainer
+ | |-- HeaderRowContainer
+ | `-- FooterContainer
+ `---- BodyRowContainer
+
+ AbstractRowContainer is intended to contain all common logic
+ between RowContainers. It manages the bookkeeping of row
+ count, makes sure that all individual cells are rendered
+ the same way, and so on.
+
+ AbstractStaticRowContainer has some special logic that is
+ required by all RowContainers that don't scroll (hence the
+ word "static"). HeaderRowContainer and FooterRowContainer
+ are pretty thin special cases of a StaticRowContainer
+ (mostly relating to positioning of the root element).
+
+ BodyRowContainer could also be split into an additional
+ "AbstractScrollingRowContainer", but I felt that no more
+ inner classes were needed. So it contains both logic
+ required for making things scroll about, and equivalent
+ special cases for layouting, as are found in
+ Header/FooterRowContainers.
+
+
+ == The Three Indices
+
+ Each RowContainer can be thought to have three levels of
+ indices for any given displayed row (but the distinction
+ matters primarily for the BodyRowContainer, because of the
+ way it scrolls through data):
+
+ - Logical index
+ - Physical (or DOM) index
+ - Visual index
+
+ LOGICAL INDEX is the index that is linked to the data
+ source. If you want your data source to represent a SQL
+ database with 10 000 rows, the 7 000:th row in the SQL has a
+ logical index of 6 999, since the index is 0-based (unless
+ that data source does some funky logic).
+
+ PHYSICAL INDEX is the index for a row that you see in a
+ browser's DOM inspector. If your row is the second 
+ element within a  tag, it has a physical index of 1
+ (because of 0-based indices). In Header and
+ FooterRowContainers, you are safe to assume that the logical
+ index is the same as the physical index. But because the
+ BodyRowContainer never displays large data sources entirely
+ in the DOM, a physical index usually has no apparent direct
+ relationship with its logical index.
+
+ VISUAL INDEX is the index relating to the order that you
+ see a row in, in the browser, as it is rendered. The
+ topmost row is 0, the second is 1, and so on. The visual
+ index is similar to the physical index in the sense that
+ Header and FooterRowContainers can assume a 1:1
+ relationship between visual index and logical index. And
+ again, BodyRowContainer has no such relationship. The
+ body's visual index has additionally no apparent
+ relationship with its physical index. Because the  tags
+ are reused in the body and visually repositioned with CSS
+ as the user scrolls, the relationship between physical
+ index and visual index is quickly broken. You can get an
+ element's visual index via the field
+ BodyRowContainer.visualRowOrder.
+
+ Currently, the physical and visual indices are kept in sync
+ _most of the time_ by a deferred rearrangement of rows.
+ They become desynced when scrolling. This is to help screen
+ readers to read the contents from the DOM in a natural
+ order. See BodyRowContainer.DeferredDomSorter for more
+ about that.

+/**
+ * A data grid view that supports columns and lazy loading of data rows from a
+ * data source.
+ * 
+ * 
    Columns
    
+ * 
    
+ * Each column in Grid is represented by a {@link Column}. Each
+ * {@code GridColumn} has a custom implementation for
+ * {@link Column#getValue(Object)} that gets the row object as an argument, and
+ * returns the value for that particular column, extracted from the row object.
+ * 
    
+ * Each column also has a Renderer. Its function is to take the value that is
+ * given by the {@code GridColumn} and display it to the user. A simple column
+ * might have a {@link com.vaadin.client.renderers.TextRenderer TextRenderer}
+ * that simply takes in a {@code String} and displays it as the cell's content.
+ * A more complex renderer might be
+ * {@link com.vaadin.client.renderers.ProgressBarRenderer ProgressBarRenderer}
+ * that takes in a floating point number, and displays a progress bar instead,
+ * based on the given number.
+ * 
    
+ * See: {@link #addColumn(Column)}, {@link #addColumn(Column, int)} and
+ * {@link #addColumns(Column...)}. Also
+ * {@link Column#setRenderer(Renderer)}.
+ * 
+ * 
    Data Sources
    
+ * 
    
+ * Grid gets its data from a {@link DataSource}, providing row objects to Grid
+ * from a user-defined endpoint. It can be either a local in-memory data source
+ * (e.g. {@link com.vaadin.client.widget.grid.datasources.ListDataSource
+ * ListDataSource}) or even a remote one, retrieving data from e.g. a REST API
+ * (see {@link com.vaadin.client.data.AbstractRemoteDataSource
+ * AbstractRemoteDataSource}).
+ * 
+ * 
+ * @param 
+ *            The row type of the grid. The row type is the POJO type from where
+ *            the data is retrieved into the column cells.

+         * ratio, the implicit expand ratio is removed, and only the defined
+         * expand ratios are taken into account.
+         * 
    
+         * If a column has a defined width ({@link #setWidth(double)}), it
+         * overrides this method's effects.
+         * 
    
+         * Example: A grid with three columns, with expand ratios 0, 1
+         * and 2, respectively. The column with a ratio of 0 is exactly
+         * as wide as its contents requires. The column with a ratio of
+         * 1 is as wide as it needs, plus a third of any excess
+         * space, bceause we have 3 parts total, and this column
+         * reservs only one of those. The column with a ratio of 2, is as wide
+         * as it needs to be, plus two thirds of the excess
+         * width.
+         * 
    
+         * This action is done "finally", once the current execution loop
+         * returns. This is done to reduce overhead of unintentionally always
+         * recalculate all columns, when modifying several columns at once.

From 48904a34a20f2d501da1b6055143fd73b5b90d50 Mon Sep 17 00:00:00 2001
From: Jouni Koivuviita 
Date: Sun, 14 Dec 2014 01:07:51 +0200
Subject: Grid theme API changes and style fixes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Renamed decorative element style names:
- “headercorner” -> “header-deco”
- “footercorner” -> “footer-deco”
- “horizontalscrollbarbackground” -> “horizontal-scrollbar-deco”

The “-stripe” style name is now added for odd rows, not even (like in
all Table themes).

Re-implemented the Base mixins for Grid and Escalator. They are now
used for all themes, which should make future development easier
because things should only be implemented in one place.

This change makes the theme also less brittle hopefully, because it
reduces the amount of pixel calculations for paddings etc. and relies
more on plain CSS.

The Base theme now offers many variables for extending themes. This
reduces unnecessary CSS output, and makes it easier to maintain
multiple themes for the Grid.

Added a box-shadow and box-sizing mixins to Base.

Converted all CSS comments to Sass comments.

Subject: Fix regressions in Grid SCSS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix regressions from previous Grid style patch:
- Typo in selector (dot instead of comma)
- “active” style renamed to “focused”
- Scrollbar border styling moved from Valo (was working) to Base (now
all themes work the same)

Change-Id: I778de73027f0cb9def1fb93e5188f494f0a49639

From 7efa1d6ec145aa48fc75fbdc9e403faf478e7f96 Mon Sep 17 00:00:00 2001
From: Leif Åstrand 
Date: Thu, 8 Jan 2015 22:21:42 +0200
Subject: Handle generated method flags in a unified way (#15373)

Refactor existing functionality without functional changes to make it
easier to add support for the @BackgroundMessage annotation added in a
separate commit.

Change-Id: I27454ba44af4b7b3b7beccf29b12e22bf9f75a86

Subject: Fix Grid handling state changes and RPC calls deferred (#16188)

Some column changes in Grid were not correctly handled by the
RpcDataProviderExtension. These cases are now correctly handled.

+/**
+ * Base class for Renderers with all client-side logic implemented using
+ * JavaScript.
+ * 
    
+ * When a new JavaScript renderer is initialized in the browser, the framework
+ * will look for a globally defined JavaScript function that will initialize the
+ * renderer. The name of the initialization function is formed by replacing .
+ * with _ in the name of the server-side class. If no such function is defined,
+ * each super class is used in turn until a match is found. The framework will
+ * thus first attempt with com_example_MyRenderer for the
+ * server-side
+ * com.example.MyRenderer extends AbstractJavaScriptRenderer class.
+ * If MyRenderer instead extends com.example.SuperRenderer , then
+ * com_example_SuperRenderer will also be attempted if
+ * com_example_MyRenderer has not been defined.
+ * 
    
+ * 
+ * In addition to the general JavaScript extension functionality explained in
+ * {@link AbstractJavaScriptExtension}, this class also provides some
+ * functionality specific for renderers.
+ * 
    
+ * The initialization function will be called with this pointing to
+ * a connector wrapper object providing integration to Vaadin with the following
+ * functions:
+ * 
      
+ * 
    • getRowKey(rowIndex) - Gets a unique identifier for the row
+ * at the given index. This identifier can be used on the server to retrieve the
+ * corresponding ItemId using {@link #getItemId(String)}.
      • 
+ * 
    
+ * The connector wrapper also supports these special functions that can be
+ * implemented by the connector:
+ * 
      
+ * 
    • render(cell, data) - Callback for rendering the given data
+ * into the given cell. The structure of cell and data are described in separate
+ * sections below. The renderer is required to implement this function.
+ * Corresponds to
+ * {@link com.vaadin.client.renderers.Renderer#render(com.vaadin.client.widget.grid.RendererCellReference, Object)}
+ * .
      • 
+ * 
    • init(cell) - Prepares a cell for rendering. Corresponds to
+ * {@link com.vaadin.client.renderers.ComplexRenderer#init(com.vaadin.client.widget.grid.RendererCellReference)}
+ * .
      • 
+ * 
    • destory(cell) - Allows the renderer to release resources
+ * allocate for a cell that will no longer be used. Corresponds to
+ * {@link com.vaadin.client.renderers.ComplexRenderer#destroy(com.vaadin.client.widget.grid.RendererCellReference)}
+ * .
      • 
+ * 
    • onActivate(cell) - Called when the cell is activated by the
+ * user e.g. by double clicking on the cell or pressing enter with the cell
+ * focused. Corresponds to
+ * {@link com.vaadin.client.renderers.ComplexRenderer#onActivate(com.vaadin.client.widget.grid.CellReference)}
+ * .
      • 
+ * 
    • getConsumedEvents() - Returns a JavaScript array of event
+ * names that should cause onBrowserEvent to be invoked whenever an event is
+ * fired for a cell managed by this renderer. Corresponds to
+ * {@link com.vaadin.client.renderers.ComplexRenderer#getConsumedEvents()}.
      • 
+ * 
    • onBrowserEvent(cell, event) - Called by Grid when an event
+ * of a type returned by getConsumedEvents is fired for a cell managed by this
+ * renderer. Corresponds to
+ * {@link com.vaadin.client.renderers.ComplexRenderer#onBrowserEvent(com.vaadin.client.widget.grid.CellReference, com.google.gwt.dom.client.NativeEvent)}
+ * .
      • 
+ * 
    
+ * 
+ * 
    
+ * The cell object passed to functions defined by the renderer has these
+ * properties:
+ * 
      
+ * 
    • element - The DOM element corresponding to this cell.
+ * Readonly.
      • 
+ * 
    • rowIndex - The current index of the row of this cell.
+ * Readonly.
      • 
+ * 
    • columnIndex - The current index of the column of this cell.
+ * Readonly.
      • 
+ * 
    • colSpan - The number of columns spanned by this cell. Only
+ * supported in the object passed to the render function - other
+ * functions should not use the property. Readable and writable.

Subject: Fixes an issue with HeightMode.ROW (#16191)

If the server-side set the height mode as row on init, the height
was miscalculated. This happened on the client side in some
special situations.

Also changes one offsetHeight to bounding box height.

Subject: Fix grid row borders and cell widget vertical alignment (#16200)

Previously the top-border for the first body row in the grid was
hidden, which caused it to blink during scrolling, when the first-child
element is moved using transforms. Moving the border to the bottom of
the cell seems to have to negative side-effects.

Fixes vertical alignment for contained widget renderers. All DIV
elements are rendered as inline-blocks by default (same as all
.v-widget elements).

Subject: Fixes exception when scrolled down and removing header/footer row
 (#15411)

This is somewhat bad patch for something that should be done with a some kind
of lazy/finally functionality, where these kinds of operations are made JIT,
instead of eagerly whenever called.
