Hi,
Can anyone tell me why I get the following exception:
java.lang.NullPointerException
at javax.media.j3d.WakeupCriterion.cleanTree(WakeupCriterion.java:64)
at
javax.media.j3d.BehaviorScheduler.doWork(BehaviorScheduler.java:131)
at javax.media.j3d.J3dThread.run(J3dThread.java:248)
It occurs, when I duplicate a BranchGroup and attach it again to the locale.
If I don't put it back in the origianl scenegraph it works fine...
Thanks,
Chris.
PS:
I'm using jdk1.3rc1 and j3d1.2beta1 on Windows NT4.0.
