AlphaBehavior on an ActorContainer does not affect children

[arnuschky]

The code below does not fade in the children of the actor container. Instead, they appear on screen right away. Expected would be that the container and its children fade in together.

If I change the behavior to another one, ie a RotateBehavior, the code works as expected (and as described in the documentation): the behavior rotates the container and all its children.

            var background = (new CAAT.Actor()).
               setBackgroundImage("background", true).
               setScale(.8, .6);

            var someimage = (new CAAT.Actor()).
               setBackgroundImage("someimage", true);

            var container = (new CAAT.ActorContainer()).
               setSize(background.width, background.height).
               centerAt(director.width / 2.0, director.height / 2.0).
               enableEvents(false).
               addBehavior((new CAAT.AlphaBehavior()).
                  setValues(0, 1).
                  setFrameTime(scene.time, 3000).
                  setInterpolator((new CAAT.Interpolator).
                     createExponentialInInterpolator(6, false)));

            container.addChild(background);
            container.addChild(someimage);

Alpha has two different ways of application:

• not affecting children (default)
• affect all children: call setGlobalAlpha(bool) on the container to enable
  it.

OK, great, that explains it. Must have missed that when I was browsing
the code.

Thanks a bunch
