I have a JTable for each item in a JComboBox. The JTable related to the selected JComboBox item is put into a JPanel. Before adding it to the JPanel, I made sure to remove the previous table.
My problem is that when I choose a different item in the JComboBox, the new JTable won't show until I resize the window or do something to force it to refresh. How can I get it to refresh automatically?

JPanel.invalidate() didn't seem to work, but JPanel.validate() did. Thanks.
However, I'm having one more issue out of this. JPanel contains two JTables. When I call JPanel.validate(), it seems to "reload" or "repaint" the first table, but not the second. Any clue on how to do this?

2 panels, one for each JTable.
panel 3 holds panel1 and panel2 (both JTables)
frame.setContent(panel3);
.validate() panel3 would refresh both?
correct me if i'm wrong on this one. not testing this in code.

Are JPanels the only way to "customize" Layouts? BorderLayout, GridLayout and FlowLayout all seem so restrictive that I am at the point of having panel over panel over panel - so on and so forth - to make my GUI arrange things in a more designed and not so boxed way?
