i think i've chosen the longest way to add the deletion onto my system, is there any other way which is more efficient ? and im wondering why only mPane.JTextFields are working, but the rest like lPane.JTextFields aren't working ?

.
.    
menuItemDelete = new JMenuItem();
         menuItemDelete.setText("Delete");
         menuItemDelete.setMnemonic(KeyEvent.VK_D);
         menuItemDelete.addActionListener(
                            new DeleteActionAdapter(this));
         menuEdit.add(menuItemDelete);
      
.

.
	// create objects for each panels or classes to call theirs panel to add into contentPane panel
      MainTabbed mPane = new MainTabbed();
      DiverTabbed dPane=new DiverTabbed();
      LocationTabbed lPane=new LocationTabbed();
      BuddyTabbed bPane= new BuddyTabbed();
      SearchTabbed sPane= new SearchTabbed();
      
      JTextField virtual = new JTextField();

          DeleteActionAdapter(UIAFrame adaptee){
            this.adaptee = adaptee;
         }

Well, replace selection only replaces selected text. Why are you not using setText()?

You may want to consider grouping the text entry components into a collection (List or Map perhaps) to make mass operations like that easier to handle.
