universal joint and callback

I can't manage to make a rigid joint on pin 0 with an universal joint
It works for
joint->setCallbackAccel(joint->calculateStopAlpha1(0.0f),1);

but not for the pin 0

I don't what i do wrong

...

why not use the RigidJoint I have included with OgreNewt?

Well in fact, it was just a try to make rigid some axis.
Later, i will want to make them normal.

hmm, might be a bug in the OgreNewt implementation of the callback then... when I have time I'll take a look into it.
