I would greatly appreciate it if someone could help me out. I am trying to
use picking to get the transform group of one of the objects in my scene.
Right now when I click anywhere inside the application I get this error:
Exception occurred during Behavior execution:
java.lang.NullPointerException
at javax.media.j3d.BehaviorRetained.wakeupOn(BehaviorRetained.java: 283)

at javax.media.j3d.BehaviorScheduler.doWork(BehaviorScheduler.java: 168)
at javax.media.j3d.J3dThread.run(J3dTread.java: 256)
if you could give me any idea what I might be doing wrong or a better way to
do this (along with some sample code hopefully) I would be very happy.
Thanks for the help
Eric
