[away3d] away3d and TweenMax issue

[SasMaster]

I am trying to put my Object3d (cube) on tween using bezier path. No I
want also that the Cube's orientation will be to path . In TweenMAx
there is a property "orientToBezier" but when I set it to true I am
getting:
"Error #1056: Cannot create property rotation on
away3d.primitives.Cube."
Anyone has an Idea how can I manage this?
Thanks
