Position problem with CCLens3D

Position problem with CCLens3D
0.0 0



when using CCLens3D or any of the other 3D effects, it seems that their positions get reset to (0,0).
For example, you create a CCSprite and parent it to the active layer. When you move the layer, everything is just fine and the sprite is moving relative to it, but when you apply a 3D action to the sprite, it gets repositioned to (0,0) and you have to move it manually.

Is that the correct behavior for that kind of action?

Thank you.
