-= Using Vaadin with Scala
-
-You can use Vaadin with any JVM compatible language, such as Scala or Groovy.
-There are, however, some caveats related to libraries and project set-up. In the
-following, we give instructions for creating a Scala UI in Eclipse, with the
-Scala IDE for Eclipse and the Vaadin Plugin for Eclipse.
-
-. Install the link:http://scala-ide.org/[Scala IDE for Eclipse], either from an
-Eclipse update site or as a bundled Eclipse distribution.
-
-. Open an existing Vaadin Java project or create a new one as outlined in
-<<dummy/../../../framework/getting-started/getting-started-first-project#getting-started.first-project,"Creating
-and Running a Project with Eclipse">>. You can delete the UI class created by
-the wizard.
-
-. Switch to the Scala perspective by clicking the perspective in the upper-right
-corner of the Eclipse window.
-
-. Right-click on the project folder in [guilabel]#Project Explorer# and select
-"Configure > Add Scala Nature".
-
-. The web application needs [filename]#scala-library.jar# in its class path. If
-using Scala IDE, you can copy it from somewhere under your Eclipse installation
-to the class path of the web application, that is, either to the
-[filename]#WebContent/WEB-INF/lib# folder in the project or to the library path
-of the application server. If copying outside Eclipse to a project, refresh the
-project by selecting it and pressing F5.
-
-+
-You could also get it with an Ivy or Maven dependency, just make sure that the
-version is same as what the Scala IDE uses.
-
-
-You should now be able to create a Scala UI class, such as the following:
-
-
-[source, scala]
-----
-@Theme("mytheme")
-class MyScalaUI extends UI {
-  override def init(request: VaadinRequest) = {
-    val content: VerticalLayout = new VerticalLayout
-    setContent(content)
-
-    val label: Label = new Label("Hello, world!")
-    content addComponent label
-
-    // Handle user interaction
-    content addComponent new Button("Click Me!",
-      new ClickListener {
-        override def buttonClick(event: ClickEvent) =
-          Notification.show("The time is " + new Date)
-      })
-  }
-}
-----
-
-Eclipse and Scala IDE should be able to import the Vaadin classes automatically
-when you press CtrlShiftO.
-
-You need to define the Scala UI class either in a servlet class (in Servlet 3.0
-project) or in a [filename]#web.xml# deployment descriptor, just like described
-in
-<<dummy/../../../framework/getting-started/getting-started-first-project#getting-started.first-project.exploring,"Exploring
-the Project">> for Java UIs.
-
-ifdef::web[]
-The link:https://github.com/henrikerola/scaladin[Scaladin add-on] offers a more
-Scala-like API for Vaadin. A Vaadin 7 compatible version is under development.

-[[getting-started.scala.lambdas]]
-== Defining Listeners with Lambda Expressions
-
-Scala does not support use of lambda expressions for calling functional
-interfaces, like Java 8 does. Hence, we can't just use a lambda expression for
-the [interfacename]#ClickListener# in the example above. You can, however,
-define implicit conversions from lambda expressions to such interface
-implementations. For example, for click listeners:
-
-
-[source, scala]
-----
-implicit def clickListener(f: ClickEvent => Unit) =
-  new ClickListener {
-    override def buttonClick(event: ClickEvent) {
-      f(event)
-    }
-  }
-----
-
-You could then use a lambda expression as follows:
-
-
-[source, scala]
-----
-content addComponent new Button("Click Me!",
-  (event: ClickEvent) =>
-      Notification.show("The time is " + new Date))
