Right, so probably, somehow, the prototypes for GeometryProps do not get created properly. Hm. It's a bit outside my domain though, and it seems to be something internal to OpenSG.
Are you able trace into the create() call and see what happens there? (I'd suspect the prototype that is cloned is null.)
