onRemove not being executed in my Mediator

I have a mediator mapped to a view, nothing special. However when I remove my view the onRemove method is never executed.
My Sprite extends CasaSprite from the CasaLib and this is definitely the problem, if I use a normal Sprite everything seems fine. A problem I noticed in the CasaSprite is that it removes all the listeners on the instance of that CasaSprite before removing the instance from it's parent.

`public function destroy():void {


this._isDestroyed = true;

if (this.parent != null)


Therefor the context would never get the REMOVED_FROM_STAGE event. However, even if I reorder these onRemove still doesn't execute.

The odd thing is if I set up a REMOVED_FROM_STAGE listener on the view in the mediator, that does execute, but the onRemove doesn't.

Any thoughts?



Here's my code in the mediator.

`override public function onRegister() : void {

view.addEventListener(Event.REMOVED_FROM_STAGE, onRemovedFromStage);


private function onRemovedFromStage(event : Event) : void

trace("  [GameInstructionsMediator] onRemovedFromStage(event)"); // Traces fine


override public function onRemove() : void

trace("  [GameInstructionsMediator] onRemove()"); // Never traces

    That is weird! Does the view component, by any chance, end up back on stage just after being removed? The MediatorMap always waits one frame and checks view.stage is null before removing the mediator - this is to allow for "re-parenting".

    I just ran into the same issue and found this thread via google. shaun mentioned the "conflict". thes elines of the CasaSprite should open your eyes:

        override public function get stage():Stage {
            if (super.stage == null) {
                try {
                    return StageReference.getStage();
                } catch (e:Error) {}
            return super.stage;

    If you set the static reference to the stage in the StageReference class, the mediatorMap will never get a null value from any class extending CasaSprite
