Change panels content

[Dijkstra30]

I am trying to build a panel like this:
- it contanins a JSplitPane
- at the left I have a tree - list of employees
- at the right I have a panel which displays a "dialog" depending on the three selection - info about employees.
I want to replace that dialog with a new created one for the employee selected everytime the selection changes.

	public JComponent buildMainPanel(Employee employee) {
		[RED]rightPane = new JScrollPane(buildRightPanel(employee));	[/RED]
		leftPane = new JScrollPane(buildTree());
	
		JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,
                leftPane, rightPane);
		splitPane.setDividerLocation(150);

		Dimension minimumSize = new Dimension(20, 50);
		leftPane.setMinimumSize(minimumSize);
		rightPane.setMinimumSize(minimumSize);
        return splitPane;
	}

	private JComponent buildRightPanel(Employee employee) {
		dialog = new EditSportDialog(employee);
	        return dialog.buildContentPane();
          }

I tryed rebuilding the whole frame. I works but I just want to rebuild the right panel somehow so the tree expansion remains the same

	public void valueChanged(TreeSelectionEvent event) {
			if (tree.getLastSelectedPathComponent() == null) return;
		    String selection = tree.getLastSelectedPathComponent().toString();
		    System.out.println("The new selection is: " + selection);
		    Employee = getEmployee(selection);
		    f.getContentPane().removeAll();
		    f.getContentPane().add(mp.buildMainPanel(employee));
		    f.pack();
		    f.setVisible(true); 
		  }

How can i change the RightPanel content without rebuilding the whole frame?

Keep a reference to the JScrollPane on the right, say scrollPane, and do something like the following when the content needs to change. You may need to do a revalidate on the scrollPane too.

scrollPane.getViewPort().add( [i]new content[/i] );
