com.google.web.bindery.event.shared.EventBus.fireEvent()
Fires the event from no source. Only unfiltered handlers will receive it.
Any exceptions thrown by handlers will be bundled into a {@link UmbrellaException} and then re-thrown after all handlers havecompleted. An exception thrown by a handler will not prevent other handlers from executing. @throws UmbrellaException wrapping exceptions thrown by handlers @param event the event to fire

    SubPresenter presenter = new SubPresenter();
    SubPresenter.MyEventBinder binder = GWT.create(SubPresenter.MyEventBinder.class);
    binder.bindEventHandlers(presenter, eventBus);


    eventBus.fireEvent(new FirstEvent());
    eventBus.fireEvent(new SecondEvent());
    eventBus.fireEvent(new ThirdEvent());


    // FirstEvent has a handler in both classes, so it should be handled twice
    assertEquals(1, presenter.firstEventsHandled);
    assertEquals(1, presenter.firstEventsWithoutParameterHandled);
