I have simple GWT 2.4.0 RequestFactory application, which fails with client side exception when fire method calls.

context.checkPassword(tbLogin.getText(), ptbPasswd.getText())
        .fire(new Receiver<EmployeeProxy>() {

            @Override
            public void onSuccess(EmployeeProxy response) {
                Window.alert(response == null ?
                        "Login faild!" :
                        response.getDisplayName()
                                + " login success!");
            }

            @Override
            public void onFailure(ServerFailure error) {
                Window.alert("Somthing wrong");
            }

        });

FireBug and Chrome Developer Tools shows nothing. I just recive an alert message:

    I bet you forgot to initialize() your RequestFactory.
