Not sure, but sounds like a scope chain is being stored in the .end() call.

I've created a custom Effect called "EndEffect" that when played will call the
end() method on the target effect sequence.
I've tested this code in both the Effect.initInstance() call of the Effect and
the EffectInstance.play() method:
/**
* @private
*/
override protected function initInstance(instance:IEffectInstance):void
{
super.initInstance(instance);
var targetEffect:IEffect = effect || target as IEffect;
targetEffect.end();
targetEffect = null;
}
In my declarations I have this code:
<c:EndEffect id="explicitEndSequence" effect="{playerSequence}"/>
The effect that this effect targets (playerSequence) has an effect end event
listener like so:
<s:Sequence id="player" effectEnd="trace('effect end')">
... it contains 3 child effects
</s:Sequence>
With I play explicitEndSequence the console traces "effect end" 3 times:
effect end
effect end
effect end
Each subsequent calls it will show 3 more than the last (2nd call):
effect end
effect end
effect end
effect end
effect end
effect end
If I change the EndEffect code so that it doesn't create a local variable it
ends once correctly:
/**
* @private
*/
override protected function initInstance(instance:IEffectInstance):void
{
super.initInstance(instance);
effect.end(); // this works! Btw "effect" is a property on EndEffect
}
Why does the first code cause a memory leak and not delete the instances?
