David Lantier commented on FLEX-33740:
--------------------------------------

Yes, that's possible; may be better.=20
Adding a method was to avoid anyone to forgot super() =E2=80=A6 but I think=
 you are right, simply set removedFromStageHandler protected is more clean.
Thanks for your answer.

> It would be more safe and faster if it was possible to override the funct=
ion UIComponent::removedFromStageHandler (and also, remove) instead to have=
 to add and remove events listeners for those who extends UI classes.=20
> Have to check if new proposed method name "removedFromStage" not used by =
any component, or choose another.
> Example:
> private function removedFromStageHandler(event:Event):void
>     {
>         _systemManagerDirty =3D true;
> =09removedFromStage();     // proposition: add this call
>     }
> // proposition: new function protected, dedicated to override
> /** Override this allow to be called when this is removing from stage. Av=
oids to have to listen REMOVED_FROM_STAGE event. */
> protected function removedFromStage():void {}
