Have you compiled widgetset?

If you have any custom widgets or add-ons in use, you should recompile the widgetset as Agata noted. If the issue still persists, please do the compile with a pretty or detailed style - or better yet, run the application in GWT dev mode to see a bit better what is actually going wrong.
