That would explain the problem that I am running into... I guess it seem
the proper thing to do is to throw an exception, because my application
references all the switches via my own data structure and expects it to be
there.
My hack workaround to catch these null Shapes3D and not add them to the
Switch. This fixes the undesirable behavior... but it would be nice if I can
keep these objects in my data structure and simply have the Switch do nothing.
Thanks to all who responded.
cheers,
