AS3 Transition Manager problem

Question

I am using the TransitionManager class to pixel dissolve an image in an image gallery XML driven.

It always stops half way through the animation...I hate Adobe Tween engines, I always used TweenMax without (almost) any problem but I would like to have the pixel dissolve effect.

 var myTM:TransitionManager = new TransitionManager(container_mc);
 myTM.addEventListener("allTransitionsOutDone",swapContent);
 myTM.startTransition({
 type:PixelDissolve, direction:Transition.OUT,  duration:1,easing:None.easeOut,xSections:200, ySections:200
 });

Any suggestion?
