Hello,

We're having a problem using the request factory in GWT 2.5 RC1. When 
calling *rejectBankCheck() *on the activity, it happens that there are bean 
validation errors. The service method corresponding to this request call is 
not invoked. By correcting the errors on the UI and clicking on a button, *
rejectBankCheck()* is called again. This time, the receiver gets *onSuccess(). 
*Everything looks fine, but I can see that both,* onSuccess()* and the 
service method corresponding to *rejectBankCheck()*, are invoked twice!

public void rejectBankCheck(String remarks) {
   request.rejectBankCheck(entity, remarks)
      .fire(new Receiver<ProtocolProxy>() {

          @Override
          public void onSuccess(ProtocolProxy response) {
        display.onRejectSuccess();
  }
          @Override
          public void onConstraintViolation(Set<ConstraintViolation<?>> 
violations) {
                display.setConstraintViolations(violations);
          }
   });
}

My first intention was to split this in two steps:

   1. initialize the receiver when the activity starts
   2. when the user clicks on the button, just call *fire()* on the request 
   context

This isn't possible, because the parameter *remarks *of the method is a 
user input and can change between the two invocations. So I have to call 
*request.rejectBankCheck(entity, 
remarks)* every time the user clicks.

Here are my questions:

   1. Is this a bug or a feature of the request factory? At the moment, I 
   cannot see when this behaviour would be necessary or of any help.
   2. Can anyone see a workaround for this?

Thank's for your help!
