Why when starting GWT in debug mode, my break points don't break

Question

I am using Eclipse 3.4.2 with the latest GWT. The IDE doesn\'t even switch to Debug Perspective automatically.

Answer 1

Changing the JDK didn't help in my case, but I have finally found out what's wrong.

When moving from GWT 1.7 to 2.0 the old GWT classes will stay on the war ouput. They must be manually deleted in order for 2.0 to kick in.
