Recreating scene graph with VisAD


I have a question regarding recreating the scene graph with VisAd.  I am
working on an application in which an object is created and a scene graph
is created (somehow) and then when that file is closed, the scene graph is
destroyed.  Then, when I try to open a new file in the same application I
run into a null pointer exception because in the DisplayRendererJ3D class,
when the renderer tries to access the view and vpTrans transform group.  

The question is, how do I recreate the scene graph if it becomes destroyed
in the process of opening and closing new files?

Thanks in advance...
