GWT client can't build with GWT 2.5.0-rc1

[dhoffer]

I tried to update my GWT/Atmosphere app to 2.5.0-rc1 today and got this error. Looks like its using GeneratorExt that was removed?

When GWT 2.5.0 becomes the current stable release we can update Atmosphere-GWT

[dhoffer]

I'd like to be able to use the new faster compile/debug features of GWT now if possible. Do you think this part of GWT will change in 2.5.0 final?

[duns]

I agree, if this could be fixed we can at least try if there are any other problems in atmosphere 1.0 and gwt 2.5.0

[rickdong]

looks like the GeneratorExt has been renamed to IncrementalGenerator in GWT 2.5.0-rc1. See ref http://code.google.com/p/google-web-toolkit/issues/detail?id=7626. This should probably be an easy fix?

[rickdong]

Now that the gwt 2.5GA is out, looks like this fix would probably go into the 1.1.0 release of the atmosphere-gwt-project. Does anyone knows when would that be?
