Get Position only giving me 0.0

I have a class which I want to mount another objcet to, but when I do I see the mounted object fly across the screen for a split second as it goes to mount. If I try to set the mounted object's inital position to the parents position I only get 0,0 for the parents position.

The parent is moving as I am getting position.

Has anyone encountered this?

I have used getPosition(), getRenderPostion() they all result with 0,0
Am I doing this wrong?

Is there maybe a way to hide the mounted object until it is mounted?
