[JAVA3D] Multiple Parent Exception

[K.R.Karthikeyan]

Hi All,        I have a createSceneGraph() method . In that method i build the whole structure. Inside that method i add a behavior object. This behavior is my own class which is a sub class of the Behaviour class. On click of some button I call this createSceneGraph() method again. So wat happens is that the behavior object is again created & added.   Instaed of creating it again & again...I thought of creating it only once say in the Initailze() & just add the object in the createSceneGraph(). But i'm getting a MultipleParentException.   Branch Group         |  Transform Group ( to this TG i add few Shape3D objects & my behavior)   Inside the createSceneGraph()...I recreate all objects. But i don't want to create the Behavior object again.   How can i aviod this ???   Thanks in Advance, Karthik
