Setting selection in table by code

Question

Hi,
I'm trying to set the selction interval in code using setSelectionInterval(x, x) on a JTable ListSelectionModel without success. Nothing gets selected.
Any ideas?

Not really any suggestions... the following code works for me:
        final JFrame test_frame = new JFrame("Test");
        test_frame.getContentPane().setLayout(new BoxLayout(test_frame.getContentPane(), BoxLayout.Y_AXIS));
        JPanel panel = new JPanel(new SpongyLayout(SpongyLayout.Orientation.HORIZONTAL, false));
        test_frame.getContentPane().add(panel);
        final JTable table = new JTable(new Object[][]{new Object[]{"A", "B"},
                                                 new Object[]{"C","D"},
                                                 new Object[]{"E","F"},
                                                 new Object[]{"G","H"}}, new Object[]{"1","2"});
        table.getSelectionModel().setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
        panel.add(new JScrollPane(table));
        JButton b = new JButton("Select 1 & 2");
        panel.add(b);
        b.addActionListener(new ActionListener()
            public void actionPerformed(ActionEvent e)
                table.getSelectionModel().setSelectionInterval(1,2);
        b = new JButton("Select 0, 2 & 3");
        panel.add(b);
        b.addActionListener(new ActionListener()
            public void actionPerformed(ActionEvent e)
                table.getSelectionModel().setSelectionInterval(0,0);
                table.getSelectionModel().addSelectionInterval(2,3);
        b = new JButton("Deselect");
        panel.add(b);
        b.addActionListener(new ActionListener()
            public void actionPerformed(ActionEvent e)
                table.getSelectionModel().removeSelectionInterval(0,3);
        test_frame.pack();
        test_frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        AWTUtilities.centerWindow(test_frame, null);
        test_frame.setVisible(true);We'll need more information on exactly what you're doing which is unusual enough to break the API. :)
