i've read that http://code.google.com/p/google-web-toolkit/issues/detail?id=3946,
so i'm using a 2.4 SDK version
some advice?

[Bruno]

Were you ever able to resolve this, I'm having the same issue?

[Colin Alworth]

Also GWT 2.4, and is it possible you have more than just 2.4 on the classpath?

Do you have the GWT-Incubator on your classpath? I've seen cases where the incubator's extremely outdated ClientBundle generators try to take over and end up just breaking things.

Otherwise, can you share the full log that you are seeing?
