I have VTK and Java working on SGI and Linux but an having some trouble with 
the following.  I create a vtkPanel and then add actors to it which are 
displayed and I can interact with them.  But I can only interact with the 
actors added in the same function where new vtkPanel was called.  If I 
create the Panel and pack it, and then add actors when a button is pushed 
they are not viewable or interactive but they do exist because I can do 
getRenderer().GetActors() and then list the actors.

When I try to interact with the actors I get
Exception occurred during event dispatching:
