Widgetset does not contain implementation Timeline

I recently upgraded my application to Vaadin 7 and tried to test the timegraph Add-On.

I followed the Add-On instructions, however I get following error instead of the timeline shown:

I recompiled the widgets without any issues.

Any ideas?

Timeline is not available for Vaadin 7 as a separate add-on. A Vaadin 7 version is included in the Charts add-on.


Actually I used Charts Add-On.

I figured out what the issue was.

I had to add the reference to the widgetset in the web.xml
