I am not removing any event listeners. Here's how I am adding them.
endDate.addEventListener(MouseEvent.CLICK, barClick)
private function barClick(event:MouseEvent):void{
var Event:TextEvent = new TextEvent("barClick");
var myDate:Date = new Date();
Event.text = myDate.getMilliseconds().toString();
dispatchEvent(Event);
}
I figured that when you remove a child that it would remove any event
listeners that were on that child. I wrote this in a loop through the
children:
if (this.getChildAt(0).hasEventListener("MouseEvent.CLICK")){
this.getChildAt(0).removeEventListener("MouseEvent.CLICK", barClick );
}
When I debugged that if statement was never true. I also commented
out all of my addEventListener code and the app still eats up memory. :(
Alex, I read your garbage collection and memory leak posts. I
automated changing my data providers and turning flex book pages. I
got to 608 megs before there was heaving pagging and i stopped it. It
seems when I change dataproviders my app likes to take up a chunk of
10 megs of memory at a time.
When I automate Ely's Anatomy flex book on its own it takes up around
100k a second and doesn't seem to top out. I wonder if this could
have to do with his component? I doubt it though, hes like a super
genius and I'm new to AS3; so it's probably me.
I'm willing to try anything and everything to get this fixed!
Thanks for your response.
