[Papervision3D] Tweener not executing onRollover

[Justin Lawerance Mills]

One approach that you can use requires a delegate such as this blokes  
class below, you can then pass the cube in the addEventListener, I am  
not saying it is ideal but it does work

{

     public class Callback
     {

         public static function create( handler: Function,...args):  
Function
         {

             return function(...innerArgs):void
             {

                 handler.apply(this, innerArgs.concat(args));

             }

         }

     }

}
