[Tween: Property backgroundAlpha not found on mx.containers.VBox and there is no default value.]

Hi,

 

I have a very simple application where I want to tween the `backgroundAlpha` of a VBox using TweenLite.

 

I'm using the following code:

TweenLite.to(box1, 2, {backgroundAlpha:0.4});

But when I try to run my movie, I get the following error:

Property backgroundAlpha not found on mx.containers.VBox and there is no default value.

I'm guessing it is because backgroundAlpha is set using `setStyle` not directly... so that is causing the issue?

 

So how do you do it in TweenLite or TweenMax to set it?

 

Thanks for your replies..
