my first guess would be you forgot to register for the Action traversals
in your MyGeometry::initMethod(). There are two examples in the system
that I know about: OpenSG/Examples/Cubes and
OpenSG/Examples/TessalationCubes, the second might be more relevant for
you since it shows how to correctly derive from the Geometry class.
