I want to write a web application that triggers the default email client of the user to send an email. Thus, I created a Link, that leads to an URL conforming to the mailto URI scheme ( http://en.wikipedia.org/wiki/Mailto ): Link emailLink = new Link("Send Email", new ExternalResource("mailto:someone@example.com")); However, instead of using a Link, I want to provide a Button that allows to trigger the respective functionality. But, for buttons I cannot set an ExternalResource to be opened. Does anybody know to solve this problem for Buttons, or how to create a Link that looks and behaves

With Vaadin Grid, I want to generate multiline cells for every cell that have more content in cell that overlaps its width. I have allready tried: java \n new line character and CSS stylings like white-space: pre; but it does not seem to work. (This solution worked for Table) custom renderer setRenderer(HtmlRenderer) with </br> tags and different CSS display settings Desired result: Vaadin Grid still doesn't have native support for multiline columns but you can try some improvisation, on example I suggest to see the Vaadin forum discussion on the link: Grid - How to display multiple lines in

Has anyone tried implementing a web application with Clojure ( using Compojure ) and Vaadin ? I had seen an article on using Clojure with JWT for creating web apps. Vaadin is based on GWT so you get a lot of the advantages of GWT ( though Vaadin is completely Server-centric). And Clojure gives the advantage that you can use any Java Based Framework, so what thoughts on the Clojure + Vaadin based web application ? I've created an article in Vaadin Trac wiki describing such integration: http://dev.vaadin.com/wiki/Articles/ClojureScripting Yes, created youcaneatat.com entirely in Clojure and

I created a spring boot application having REST web services and jpa dependencies. The application runs on its own as a standalone application. I'm trying to add UI layer using vaadin as a separate project that uses the services from the sring boot project. Is there an easy way to make the spring boot application as a library jar that can be included in other projects. I searched the forum and found some threads that advised not using spring boot but instead using the spring framework to create the library. Just wanted to check if there are any examples how this can be done in Spring boot.

I've created a new Vaadin (6.6.5) project in eclipse and I've tried to deploy it on JBoss 7.0 but it gives me a GWT ClassNotFoundException Caused by: java.lang.ClassNotFoundException: com.google.gwt.user.client.ui.HasWidgets from [Module "deployment.test.war:main" from Service Module Loader] at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:191) at org.jboss.modules.ConcurrentClassLoader.performLoadClassChecked(ConcurrentClassLoader.java:358) at org.jboss.modules.ConcurrentClassLoader.performLoadClassChecked(ConcurrentClassLoader.java:330) at org.jboss.modules

We're planning on creating a feedreader as a windows desktop- and iPad application . As we want to be able to show Websites AND to run (our own) JavaScript in this application, we thought about delivering the application as HTML/CSS/JavaScript, just wrapped by some .NET control or a Cocoa Touch webbrowser component. So the task at hand is to find out which framework to use to create the HTML/CSS/JS files to embed in the application. For the development of the HTML/CSS/JavaScript we would be happy to use Vaadin, GWT, or some other framework, as we're a lot better with Java than with JS. We
