The example source was copied from JVx VaadinUI and it has an option to show or save the content. I simply forgot to copy one method :) I've changed the example for you - <a href="http://blog.sibvisions.com/wp-content/uploads/2014/12/VaadinJVxSet_v2.zip" rel="nofollow">download</a>. You're right!

I've changed the example for you - download.

I see how the extensions and connectors work now, and your example runs perfectly in IE, ffox and chrome. Is there some reason that this extension would be sensitive to file types or file extensions? The ContactsForm.xls downloads properly, but when I add a PNG file in the same location (com.example.vaadinjvxset) and duplicate the ContactsForm code to another button and listener, the download doesn't work. There are no errors on my console, just no action in the browser for the PNG file I put in there. Wonderful example rjahn, thanks for your help!

Simply import the project and deploy it. The application is a standard Vaadin 7.3.5 application, created with Vaadin Eclipse plugin - no magic! The DownloaderExtension was copied from JVx.vaadin and widgetset was created with Eclipse plugin - no extra ant file. I hope it'll help :) A zip archive with a complete Eclipse project and demo application is available here. Simply import the project and deploy it.

I am a Vaadin developer, but have only used the standard server-side components until now. There must be some other step involved in using this that first-time widget users are not aware of. I say that because in your reply you mention JVx.vaadin and adding source files to my widget set, and I don't understand either of those statements. I know my project has a .gwt.xml file that defines my (empty) widgetset, and I have added jar file references to that file with an inherits line, but my knowledge ends there. I will try and solve my problem by the usual google searches, but the widgetset tutorials I have found go into things like connectors and so on, and I suspect that just doesn't apply here. I need to get my feet wet a little more slowly. I think he did what I did, which is just include the source in my source tree and instantiate the object in my UIs init() method.
