Hi Mona, Why not extend the Switch class with your own that implements the behaviour you expect. Then, you Switch class can maintain the indexing your prefer, keeping track of which nodes in the underlying switch are null.

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, Mona ================================================================== Mona Wong-Barnum National Center for Microscopy and Imaging Research University of California, San Diego http://ncmir.ucsd.edu/ "Circumstances don't make a man, they reveal him" -- James Allen ================================================================== =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
