Hi everyone!
I'm building a Virtual Theater app, and sometimes need to change scenes.
I'm doing this by using the repaceBranchGraph method in the locale class.
I have only one locale in my app an when I need to change scenes, I just
replace their BranchGroup root Node.
I have two scenes A and B. When I change from A to B it works, but when I
change back from B to A I get this exception:
java.lang.NullPointerException

at javax.media.j3d.Traverser.run(Traverser.java:2084)
don't this the problem is the replace method, cause I tried with the
addBracchGraph and detach, and the result is the same.
I think it only happends when I return to an scene where I've been before.
Can some body help me? I think I doing nothing wrong.
Thanks
