Hi all,
i'm facing a litlle problem using places activities and events... Have
tried multiple tricks but not luck .
My problem:
i try to fire an event from the activity but my widget does not catch it
since its not loaded (I mean that if i fire this event once the widget's
loaded everything works fine).
Here is my Gin configuration:
@Override
protected void configure()
{
bind(EventBus.class).to(SimpleEventBus.class).asEagerSingleton();
bind(PlaceHistoryMapper.class).to(MyPlaceHistoryMapper.class).in(Singleton.class);
bind(ActivityMapper.class).to(MyActivityMapper.class).in(Singleton.class);
bind(MyActivity.class);
install(new
GinFactoryModuleBuilder().build(MyActivityMapper.Factory.class));
}
@Provides
@Singleton
public PlaceController getPlaceController(EventBus eventBus)
{
return new PlaceController(eventBus);
}
@Singleton
@Provides
public ActivityManager provideActivityManager(ActivityMapper
activityMapper, EventBus eventBus)
{
return new ActivityManager(activityMapper, eventBus);
}
in MyActivity:
@Inject
private MyWidget myWidget;
@Inject
private EventBus globalEventBus;
@Override
public void start(AcceptsOneWidget panel, EventBus eventBus)
{
panel.setWidget(myWidget);
MyEvent event = new MyEvent();
event.setAction(MyEvent.Action.INIT);
globalEventBus.fireEvent(event);
}
I also try two different ways of binding events in my widget, during onLoad
and in constructor:
During onLoad:
@Inject EventBus eventBus;
@Override
protected void onLoad()
{
handlersRegistration.add(eventBus.addHandler(MyEvent.TYPE, this));
}
In constructor:
private EventBus eventBus;
@Inject
public MyWidget(EventBus eventBus)
{
this.eventBus = eventBus;
// registration of handlers
handlersRegistration = new ArrayList<HandlerRegistration>();
// register myself has a listener of different event TYPE
handlersRegistration.add(eventBus.addHandler(MyEvent.TYPE, this));
...
}
Am I doing something w rong or missing something?
Thks in advance
Tugdual
