RequestFactory: error.getExceptionType() returns null in Receiver#onFailure

In the server side i have:

public void throwException() throws Exception {
        throw new NullPointerException("fslkdjflks");
}

in the client side i have:

_requestFactory.myService().throwException().fire(new Receiver<Void>() {

            @Override
            public void onSuccess(Void response) {
                // TODO Auto-generated method stub

            }

            @Override
            public void onFailure(ServerFailure error) {
                // TODO Auto-generated method stub
                Window.alert(error.getExceptionType() + " " + error.getMessage());

            }

        });

error.getExceptionType() returns null and not the type of the exception. Any idea why?

Thanks, Gilad.

Addition to Thomas post, a link how to implement it.

Implement this and you get your StackTrace and find the Problem: http://cleancodematters.com/2011/05/29/improved-exceptionhandling-with-gwts-requestfactory/

Takes five minutues and saves you much time now and in future.

The default ExceptionHandler (DefaultExeptionHandler) does not populate the exceptionType and stackTraceString. If you want them, you have to provide your own ExceptionHandler by extending RequestFactoryServlet.
