Re: Can't debug client code from Eclipse
It was a scoping problem.I needed to use a closure in the native js
method to wrap the callback, because even though passing the function ref
works in js, to run in java it needs the context.
It would be cool if the documentation explicitly called that out because i
didn't realize gwt would barf like that in developer mode. It does make
sense now though.

Re: Can't debug client code from Eclipse
Hi,
Are you sure the callback is not firing in development mode, or is the
breakpoint not being hit? If the breakpoint is not being hit, you may be
running into this issue (if you're using hotswap):
http://code.google.com/p/google-web-toolkit/issues/detail?id=4704
If you're not actually getting the callback to fire in development mode, can
you paste a code snippet that shows what you're doing?
Thanks,
Rajeev

Re: Can't debug client code from Eclipse
I'm having a similar problem though the only place breakpoints don't
seem to work is in my AsyncCallback.
I see no errors in firebug or anywhere in eclipse.
The method that accepts the callback is a native js method. the js
calls the callback onSuccess.
With compiled code, I can see this actually works, but running in
development mode, i cannot get the callback to fire at all.
please advise.

Actually I found the problem. I was setting the breakpoint on the
method definition line, i.e.:
public void onSuccess(String result) {
Those breakpoints never hit. If I place breakpoints on any lines
*within* that method, they hit just fine.
Note that under normal circumstances if you put a breakpoint on a
method line, execution will break at the immediately following line.
It seems that client-side asynchronous GWT code doesn't behave that
way. I wouldn't consider this to be a serious issue: just something
to be aware of.
Thanks for your advice.

Re: Can't debug client code from Eclipse
Actually, setting a breakpoint in async callback code should definitely work. In the sample, I set a breakpoint in the "onSuccess" method of the RPC callback, and it breaks there. Try upgrading your JDK and see if you still experience the problem.

Re: Can't debug client code from Eclipse
There have been problems with versions of JDK 1.6.0_X, where X is between 0-15, where breakpoints are not hit when debugging. However, it is odd that your server breakpoints consistently work, but your client breakpoints do not; in those cases where the JDK has been the source of the problem, the breakpoints don't work at all (on either side). What is the URL that you're pasting into your browser? Can you provide a screenshot of what the development mode view looks like (I want to make sure that there is an entry for the web browser)? What happens if you set the breakpoint in the onModuleLoad() method within your entry point?
