FadeIn and FadeOut does not apply to children even in 3.3 final

[51782381]

I add Sprite as a child to another Sprite, and let the parent Sprite runAction of FadeXXX, the child Sprite just dont follow.
I think the opacity of child is not updated during Action of FadeXXX.

did you set sprite->setCascadeOpacityEnabled(true);?
