Widget destruction impossible because of EventBus ?

Hey everyone,

I noticed that my widget still listens to events from EventBus event after I remove them from the DOM and after I clear all my references to them. I was thinking if this was because of the EventBus bus handler the widget has. Or I am missing something !

Anyway here is a simplified test illustrating this. The Event i'm using is a basic custom event and the Window.alert is there just to make sure the event is received.

class TestWidget extends Composite {

public TestWidget(final int id) {

// register to event 

EVENT_BUS.addHandler(UpdateDataEvent.TYPE, new UpdateDataEventHandler() {

public void onUpdate(UpdateDataEvent event) {

logger.log("n°" + id + " living");

}

});

initWidget(new HTML("TestWidget #" + id));

}

}

// add test widgets to DOM

TestWidget t1 = new TestWidget(1);

TestWidget t2 = new TestWidget(2);

RootaPanel.get().add(t1);

RootaPanel.get().add(t2);

// fire event

EVENT_BUS.fireEvent(new UpdateDataEvent());

// logs as expected : #1 and #2

// little break

Window.alert("Break");

// remove one widget and force the reference to null

t1.removeFromParent();

t1 = null;

// fire event

EVENT_BUS.fireEvent(new UpdateDataEvent());

// still logs #1 and #2

Any heads-up ?

Many thanks, 

Ludovit
