Re: GWT 2.0 RPC Problem

2009-10-12 Thread Zé Vicente 

In fact, I did many tests... If I compile the application I get the
same error.

For the Jars I quite sure the is ok. If I go back to GWT 1.7 it works
fine.

My scenario again:

ServeviceAAsync serviceA = GWT.create(ServiceA.class);
ServeviceBAsync serviceB = GWT.create(ServiceB.class);
ServeviceCAsync serviceC = GWT.create(ServiceC.class);

So, if  I use serviceA, it works fine. When I use serviceB or C in the
sequence, I get the exception. I can use any sequence, the second
service always crash.

Regards,
José Vicente

 Are you able to get run it in web mode (ie. after compiling using gwtc)?
 Also, try to see if you have the right jars in the classpath when starting
 up hosted mode/oophm. Perhaps you have both versions of gwt in your
 classpath?

  Hello all,

  I very happy to be able to test GWT 2.0. The new features are
  amazing The code splitting and Declarative UI are going to place
  GWT on the top of choice for UI development. I am quite sure the the
  market will require more professionals with GWT experience.

  Well, but we still have some problems to solve. In my case, I did the
  migration of my project from 1.7 to 2.0. Now I have a very strange
  behavior. My first rpc call works fine. But it does not matter which
  service I call the second time. It always crash. So, in my second rpc
  call I get an error message like that:
