Please understand that I won't have time to work on this in the next one or two weeks because right now we are all extremly busy with the Kepler M2 release, some left-overs from Eclipse Juno, etc... in addition to that we will need to move the RAP demo applications to a new server.
This includes the 3.x workbench demo with various themes, and the controls demo as a separate application. Please note that the location and URLs have changed. The available URLs can always be found on the web page above.
