DragonBones alpha not working

I have some animations made on dragonbones that have alpha on some textures, but are not working. I’ve target flash, neko and android. When I target html5 it works.

Does this occur in any of the DragonBones samples?

Yes, i saw the AnimationBaseTest. It has a progress bar, and the “head” should start and end with alpha 0.
If you look the html5 result, its ok, but on flash, for instance, it’s always opaque.
