Methods Summary
public voidvalueChanged(javax.swing.event.TreeSelectionEvent evt)
This method listens for selections in the tree and sets the values on the right hand side of the window for any selected customer. This method uses the WorkerThread since any call to get a customer value may trigger a network call if that value is yet cached in the facade.

        TreePath path = evt.getNewLeadSelectionPath();
        final Object ob = path.getLastPathComponent();

        TellerApp.notifyWait();
        if( ob instanceof CustomerNode ) {
            WorkerThread wt = new WorkerThread() {
                    String ssn, fn, ln, cid;

                    public void run() {
                        CustomerFacade cust = ((CustomerNode)ob).getCustomer();

                        try {
                            ssn = cust.getSocialSecurity();
                            fn = cust.getFirstName();
                            ln = cust.getLastName();
                            cid = "" + cust.getObjectID();
                        }
                        catch( RemoteException e ) {
                            ssn = "ERROR";
