I want to be able to save to disk the entire state of a
piece of my dialog. It's basically a listbox defined
as follows-:

public class rwd_writablevectormodel extends 
  ListControl implements WritableVectorModel,Serializable

I'm saving it to disk as follows-:

         FileOutputStream outstream = new FileOutputStream(name);
         ObjectOutputStream out = new ObjectOutputStream(outstream);
         out.writeObject(cListbox);
         out.close();

and reloading it as follows-:

            FileInputStream instream = new FileInputStream(name);
            ObjectInputStream in = new ObjectInputStream(instream);
            rwd_writablevectormodel rc=(rwd_writablevectormodel)in.readObject();

When I try to work with the loaded object (to add a listner),
I get the following exception-:

System Error:	Exception occurred during event dispatching:
System Error:	java.lang.NullPointerException
System Error:		at borland.jbcl.view.ListCore.addSelectionListener(Compiled Code)
System Error:		at borland.jbcl.view.ListView.addSelectionListener(Compiled Code)

The code to add the handler is as follows-:

      jPanelList.addSelectionListener(new
borland.jbcl.model.VectorSelectionAdapter()
      {
         public void selectionChanged(VectorSelectionEvent e)
         {
            jPanelList_selectionChanged(e);
         }
      });

Any ideas ? Am I crazy trying to writ ean entire liscontrol object to
disk and reload it ? I loved the old C++ days, when I could just dig
around the lower level code to find out why my higher level code
was dying...
