i just finished my first own example with activities/places and MVP. all
works fine but some events aren't send or received properly if i change back
to a place (from another place). but on "moduleLoad" where this place is set
as default place all works fine. i think it shouldn't make a difference if a
place/activity is started on moduleLoad (via historyHandler = new
PlaceHistoryHandler(historyMapper); historyHandler.register(placeController,
eB, defaultPlace); historyHandler.handleCurrentHistory();) or via
placeController.goTo(place); , should it?
via debugging i checked the order of event registration, event sending and
event receiving (all is executed in start(...) of the activity). the problem
is that all receiver don't receive the event if start() is executed via
goTo(place) (registration and sending works fine). But if an event is sent
after start() or within start()-executed on moduleLoad all works fine!
my activity start looks like that:
@Override
public final void start(final AcceptsOneWidget panel, final EventBus
eventBus) {
// register events - to manipulate visibility of some display areas
eventBus.addHandler(SelectedEvent.TYPE, this);
//initiate presenters -(pseudo code)
[presenter that receives SelectedEvent]
[presenter that sends SelectedEvent]
//ading presenter's asWidgets to screen -> panel.setWidget..
...
}
@Override
public final void onSelected(final SelectedEvent event) {
//do something
}
(the use case for sending this event on start is, that i want say nothing is
selected - the event's payload is null)
the problem is that neither the presenter's nor the activity's onSelected
-method is called if the start() is called via goTo. But in all cases
(checked with debugger) the registering on event occurs before sending it.
what should i do?
