using rotateProp on doorway

[darksky]

hi
i wanted to make a rotatable room. but the doorway and doorframe won't rotate (at least not visible). (see here http://www.youtube.com/watch?v=I1UCwYde7rE )

i imported mesh in model editor, put some shapes around the mesh, created a body for each shape and attached the mesh to the body. for things with just one body , like walls, it works fine, but i guess i did a mistake with the frame and doorway ( because of multiple bodies? ).

how to do it right?
