Constraining dynamically loaded objects

Well. Actually, all this stuff would be much easier to solve with bones API which will come at the end of this month.

I tried with removing the constraints at the beginning of the event handler code, applying a rotation and reconstraining the object again.

This method works fine for me, but you need to take the parent's rotation into account when you are going to apply constraint again.

I agree, using the bone API will help a lot here.
When will the beta version be available for download?
