, thats not helpful! I would sort your debugger out first!
_getDerirvedPosition thing applies to _getDeriviedOrienation, _getDerivedScale, convertLocalToWorld**, convertWorldToLocal, _getFullTransform functions as well. However simply using the *updated functions should not be a long term solution, but I can understand if you just want to get something working. This may also occur if you update a nodes transform, between updating the scene graph and rendering an object, however this is fairly unlikely if you are using renderOneFrame, unless you have some custom movableObjects that override _updateRenderQueue...
**EDIT** Just seen your latest post, I use an old version of CCS but I have not yet updated it to Ogre 2.0. But it defiantly has a bunch of _getDerived*** functions in it.
