Below is a list of the most notable changes:</p> <ul> <li>Grid is a new component for showing tabular data. It has been designed from the ground up to eventually replace the Table and TreeTable components.<br /> The most notable Grid features in @version-minor@ are: <ul> <li>Support for multiple rows in the header and footer sections.</li> <li>Renderer concept for customizing how the data in a given column is represented in the browser.</li> <li>Support for frozen columns.</li> <li>Support for inline editing of one row at a time.</li> <li>Support for components in header and footer cells.</li> <li>Hardware accelerated, touch optimized scrolling.</li> </ul></li> <li>Declarative layout support for initializing a component hierarchy from an HTML file.</li> <li>Uses GWT 2.7 for improved compilation times when using Super Dev Mode.</li> <li>@Viewport annotation for declaratively defining a mobile viewport definition for a UI.</li> <li>Captions can be configured to be displayed as HTML.</li> <li>Selects use converters when presenting itemids.</li> <li>Improved performance when server response contains no visual changing (e.g. empty polling responses).</li> <li>Unified JSON library for using the same API in both server-side and client-side code.</li> <li>Range validators and converters for additional numerical types.</li> <li>Support for fine grained add/remove item events in in-memory containers.</li> </ul> <p> For enhancements introduced in Vaadin 7.3, see the <a href="http://vaadin.com/download/release/7.3/7.3.0/release-notes.html">Release Notes for Vaadin 7.3.0</a>. </p> <h3 id="incompatible">Incompatible or behavior-altering changes in @version-minor@</h3> <ul> <li> <p>The org.json and com.google.gwt.json libraries have been replaced by elemental.json.</p> <p>JavascriptFunction.call parameter type has been changed to elemental.json.JsonArray, affecting JavaScript.addFunction, AbstractJavaScriptComponent.addFunction and AbstractJavaScriptExtension.addFunction</p> <p>Raw JSON values passed to AbstractJavaScriptComponent.callFunction and AbstractJavaScriptExtension.callFunction should be changed to use elemental.json types.</p> </li> <li>Support for Opera 12 has been dropped. Newer versions based on the Blink rendering engine are still supported.</li> </ul> <h3 id="knownissues">Known issues</h3> <ul> <li>Drag'n'drop in a Table doesn't work on touch devices running Internet Explorer (Windows Phone, Surface) (<a href="http://dev.vaadin.com/ticket/13737">#13737</a>) </li> </ul> <h3 id="limitations">Limitations</h3> <ul> <li><p>It is currently not possible to specify <tt>font-size</tt> as <tt>em</tt> or <tt>%</tt>, or layout component sizes with <tt>em</tt> (<a href="http://dev.vaadin.com/ticket/10634">#10634</a>).</p><p>This does not apply to Valo, but using em sizes to size layouts is discouraged, because it results in fractional component sizes in many cases, which might cause unwanted 1px gaps between components.</p> </li> <li>Push is currently not supported in portals (See <a href="http://dev.vaadin.com/ticket/11493">#11493</a>) </li> <li>HTTP session can not be invalidated while using push over websockets on Tomcat 7 (<a href="http://dev.vaadin.com/ticket/11721">#11721</a>) </li> <li>Cookies are not available while using websockets (<a href="http://dev.vaadin.com/ticket/11808">#11808</a>) </li> <li>Not all proxies are compatible with websockets or streaming. Use long polling to avoid these problems.</li> </ul> <h2 id="vaadin">Vaadin Installation</h2> <p> <b>Vaadin</b> is a Java framework for building modern web applications that look great, perform well and make you and your users happy. <b>Vaadin</b> is available under the Apache License, Version 2.0 (see the <tt>license.html</tt> in the Vaadin ZIP or JAR package). </p> <p> The easiest ways to install <b>Vaadin</b> are: </p> <ul> <li>If using Maven, define it as a dependency or use any of the available archetypes (only <tt>vaadin-application</tt> is available for Vaadin 7 at the time of this release) to create a new project </li> <li>If using Eclipse, use the Vaadin Plugin for Eclipse, which automatically downloads the Vaadin libraries. </li> </ul> <p> It is also available as a ZIP package downloadable from <a href="http://vaadin.com/download">Vaadin Download page</a>. </p> <h3 id="package">Package Contents</h3> <p>Inside the ZIP installation package you will find:</p> <ul> <li>Separate server-side (<tt>vaadin-server</tt>) and client-side (<tt>vaadin-client</tt>, <tt>vaadin-client-compiler</tt>) development libraries </li> <li>Precompiled widget set (<tt>vaadin-client-compiled</tt>) for server-side development </li> <li>Shared library (<tt>vaadin-shared</tt>) for both server- and client-side libraries </li> <li>Built-in themes (<tt>vaadin-themes</tt>) </li> <li>Dependency libraries provided under the <tt>lib/</tt> folder </li> </ul> <p> See the <tt>README.TXT</tt> in the installation package for detailed information about the package contents. <a href="http://vaadin.com/book">Book of Vaadin</a> (for Vaadin 7) gives more detailed instructions. </p> <p> For server-side development, copy the <tt>vaadin-server</tt> , <tt>vaadin-client-compiled</tt> , <tt>vaadin-shared</tt> , and <tt>vaadin-themes</tt> from the main folder and the dependencies from the <tt>lib</tt> folder to the <tt>WEB-INF/lib</tt> folder of your Vaadin project. (The <tt>vaadin-client-compiled</tt> is necessary if you do not wish to compile the widget set by your own, which you need to do if you use almost any add-on components.) </p> <h4 id="package.updates">Updates to the Packaging</h4> <p> Since Vaadin 7.2.0, the old vaadin-theme-compiler has been moved into a separate project and renamed to vaadin-sass-compiler. It is now included along with the other 3rd party dependencies in the ZIP package. </p> <p> For pure client-side development, you only need the <tt>vaadin-client</tt> and <tt>vaadin-client-compiler</tt> JARs, which should be put to a non-deployed project library folder, such as <tt>lib</tt> . You also need them if you compile the widget set for any reason, such as using Vaadin add-ons, or create new server-side components integrated with client-side widgets. </p> <h2 id="migrating">Migrating from Vaadin 6</h2> <p> All Vaadin 6 applications need some changes when migrating to Vaadin 7. The most obvious changes are in the application/window API and require extending either <b>UI</b> or <b>UI.LegacyApplication</b> instead of <b>Application</b>. A detailed list of migration changes are given in the <a href="https://vaadin.com/wiki/-/wiki/Main/Migrating+from+Vaadin+6+to+Vaadin+7">Vaadin 7 Migration Guide</a>. </p> <p>Any custom client-side widgets need to be ported to use the new client-server communication API, or the Vaadin 6 compatibility API.</p> <p> Vaadin 6 add-ons (ones that contain widgets) do not work in Vaadin 7 - please check the add-ons in <a href="http://vaadin.com/directory/">Vaadin Directory</a> for Vaadin 7 support. </p> <h2 id="dependencies">Vaadin @version@ Dependencies</h2> <p>When using Maven, Ivy, Gradle, or other dependency management system, all Vaadin dependencies are downloaded automatically. This is also the case when using the Vaadin Plugin for Eclipse.</p> <p> The Vaadin ZIP installation package includes the dependencies in the <tt>lib</tt> subfolder. These need to be copied to the <tt>WEB-INF/lib</tt> folder of the web application that uses Vaadin. </p> <p> The dependencies are listed in the <a href="license.html">Licensing description</a>. Some are explicit dependencies packaged and distributed as separate JARs, while some are included inside other libraries. </p> <h3>Bean Validation</h3> <p> If you use the bean validation feature in Vaadin 7, you need a Bean Validation API implementation. You need to install the implementation JAR in the <tt>WEB-INF/lib</tt> directory of the web application that uses validation. </p> <h2 id="upgrading">Upgrading from Vaadin 7.1 to Vaadin @version-minor@</h2> <p>When upgrading from an earlier Vaadin version, you must: </p> <ul> <li>Recompile your classes using the new Vaadin version. Binary compatibility is only guaranteed for maintenance releases of Vaadin.</li> <li>Unless using the precompiled widget set, recompile your widget set using the new Vaadin version.</li> </ul> <p>Remember also to refresh the project in your IDE to ensure that the new version of everything is in use.</p> <p> By using the " <tt>?debug</tt> " URL parameter, you can verify that the version of the servlet, the theme, and the widget set all match. </p> <p> <b>Eclipse</b> users should always check if there is a new version of the Eclipse Plug-in available. The Eclipse Plug-in can be used to update the Vaadin version in the project (Project properties » Vaadin). </p> <p> <b>Maven</b> users should update the Vaadin dependency version in the <tt>pom.xml</tt> unless it is defined as <tt>LATEST</tt> . You must also ensure that the GWT dependency uses the correct version and recompile your project and your widget set. </p> <p> <b>Liferay and other portal</b> users must install the Vaadin libraries in <t>ROOT/WEB-INF/lib/</b> in the portal (and remove a possibly obsolete older <tt>vaadin.jar</tt>). Additionally, the contents of the <tt>vaadin-client-compiled</tt> and <tt>vaadin-themes</tt> must be extracted to the <tt>ROOT/html/VAADIN</tt> directory in the Liferay installation. If your portal uses custom widgets, you can use <a href="http://vaadin.com/directory#addon/liferay-control-panel-plugin-for-vaadin:vaadin"> Liferay Control Panel for Vaadin</a> for easy widget set compilation.</t> </p> <h2 id="gae"> Notes and Limitations for Google App Engine </h4> </h2> <p>The following instructions and limitations apply when you run a Vaadin application under the Google App Engine.</p> <ul> <li> <p> Applications must use <b>GAEVaadinServlet</b> instead of <b>VaadinServlet</b> in <tt>web.xml</tt> . </p> </li> <li> <p> Session support must be enabled in <tt>appengine-web.xml</tt> : </p> <pre> <sessions-enabled>true</sessions-enabled></pre> </li> <li> <p>Avoid using the session for storage, usual App Engine limitations apply (no synchronization, that is, unreliable).</p> </li> <li> <p> Vaadin uses memcache for mutex, the key is of the form <tt>_vmutex<sessionid></tt> . </p> </li> <li> <p> The Vaadin <b>VaadinSession</b> class is serialized separately into memcache and datastore; the memcache key is <tt>_vac<sessionid></tt> and the datastore entity kind is <tt>_vac</tt> with identifiers of the type <tt>_vac<sessionid></tt> . </p> </li> <li> <p> DO NOT update application state when serving an <b>ConnectorResource</b> (such as <b>ClassResource</b>.<i>getStream()</i>). </p> </li> <li> <p>The application remains locked during uploads - a progress bar is not possible</p> </li> </ul> <p> For other known problems, see open tickets at developer site <a href="http://dev.vaadin.com/">dev.vaadin.com</a>. </p> <h2 id="supportedversions">Supported Technologies</h2> <p> Vaadin 7 is compatible with <b>Java 6</b> and newer.
