DiscreteDynamicsWorld is usually used instead of CollisionWorld, you can try that.
But CollisionWorld should work too, so I'll take a look today or tomorrow.

A RigidBody can be inserted into a DynamicsWorld with AddRigidBody.
A RigidBody can also be inserted into a CollisionWorld with AddCollisionObject, because RigidBody inherits from CollisionObject, but I don't know if that's semantically correct.

A DiscreteDynamicsWorld will work with anything except soft bodies and multibodies, so I'd still recommend that.

Hey, I didn't get notified by Gmail even though this is marked as important. Thank you for clarifying things for me and for the doc link. Have a nice day.
