Re: Activity how to react on event that is triggered in start-method

i think this is not the problem. first i register for event then i fetch the data that triggers the event. here is the code of start method:

    @Override
    public final void start(final AcceptsOneWidget panel, final com.google.gwt.event.shared.EventBus eventBus) {
        this.eb = new ResettableEventBus(eventBus);
        view.setPresenter(this);
        this.eb.addHandler(DynamicTableHashResolvedEvent.TYPE, this);//handler registration
        stateResolver.resolveState(((DynamicTablePlace) pc.getWhere()).getTablehash(), eb);//triggers event
        panel.setWidget(view);
    }

the event triggered in start method will be received when next event is triggered - so after the start method i am one event too "late".

Does your data fetch include the event bus in some way? If so you may be running into the problem that handler changes (adds/removes) are only applied after the current event has completed. In this case that event would be the place change eventually calling the activity start.

Sorry for the lack of references, im not at a pc

i have an activity that needs another class to resolve the state (ids to real objects) brought by current place. this class' "getData(StateObject)" is called within start-method right after registering for the class' gotData-event. But the activitie's onGotData-data method isn't called the first time. If the activity calls getData after the start method all works fine.
i have the feeling that this can't work but how to get it working? The data class need an object provided by a special kind of place (the same place as the activity starts on).
