KeyEvent doesn't trigger Tweener

Hi people,

I have a weird problem (at least for me it’s weird). I’m using Flex and AS3 (I chose Actionscript project) to make a new project. I use Tweener for all my tween animations. Well now I have written a script that when a key is pressed (left or right key) a sprite should Tween to the left or right. Now that’s not working…

I’ve pasted the code here http://pastebin.com/m46b65644 and I activate the keylisteners (function activateKeys) in another class. Works fine cause it traces everything.

Can someone please look at my code and tell me what I am doing wrong (or what I am missing)?

Thanks!!!

Jessica
