TweenEvent dispatches not always happening

I found this post on the Actionscript.org forums about TweenEvent dispatches not happening consistently.

I’ve come up against a similar problem in the past. The first thing to check is that the Tween instance does not go out of scope. For example (this is pseudo code)…

ActionScript Code:
private function doTween():void {
  var tween:Tween = new Tween(....);
  tween.addEventListener(TweenEvent.MOTION_FINISH, onFinished);
}

… will not work reliably - the tween instance goes out of scope when the function finishes (despite having an event listener attached to it) and I’ve found this unreliable. I make sure that the tween instance is always in scope:

ActionScript Code:
private var tween:Tween;
private function doTween():void {
  tween.addEventListener(TweenEvent.MOTION_FINISH, onFinished);
}

My question is this - where do I call this part


  var tween:Tween = new Tween(....);

is this what I’m meant to do:

ActionScript Code:
private var tween:Tween;
private function doTween():void {
  var tween:Tween = new Tween(....);
  tween.addEventListener(TweenEvent.MOTION_FINISH, onFinished);
}

As this doesn’t seem to make any difference. Thanks
