[Tweener] onUpdate timer

[Jesse Lucas]

Hello,

I was wondering if anyone knew of a way to stop the onUpdate timer in  
the middle of a tween?

Tweener.addTween(this._slideContainer, {x:-(959 *  
(this._slideArray.length)), time: i * .5, transition:"easeInOutQuad",  
onUpdate:this.updateSlidePosition});

I want to be able to stop the onUpdate timer with a conditional in the  
updateSlidePosition method.

Thanks!

Jesse
