I am using Swing 0.5 JTable with the DefaultTable Model.
The application contains the following panels:

JFrame containing
    JPanel containing
       JDesktopPane containing
           JInternalFrame containing
               JScrollPane containing
                   JTable

The JTable getValueAt() method is being called with
a -1 for the columnIndex. This happens both when I
use my own TableModel and when I use the DefaultTableModel.
Below is the stack trace when using the DefaultTableModel.

import com.sun.java.swing.*;
import com.sun.java.swing.table.*;
import java.awt.*;
import java.util.Vector;

public class mainFrame extends JFrame
{
    JDesktopPane lc;
    JPanel mainPanel;
    
    
    public static void main(String argv[])
    {
            // Create the main frame
          // new mainFrame().show();
            new mainFrame();
    }
    
    public mainFrame(){
        getContentPane().setLayout(new BorderLayout());
        mainPanel = new JPanel();
        mainPanel.setLayout(new BorderLayout());
        getContentPane().add("Center", mainPanel);
        lc = new JDesktopPane();
            lc.setOpaque(true);
                resize(insets().left + insets().right + 900,insets().top + insets().bottom + 700);
        mainPanel.add("Center", lc);
        mainPanel.show();
                intFrame newframe = new intFrame();
System.out.println("mainFrame:NewFrame: got a new frame: " + newframe);
        lc.add(newframe);
        mainPanel.validate();
                show();
                newframe.show();
                mainPanel.show();
    }
}

                subsystemTable.setMultipleSelectionAllowed(false);
            subsystemTable.setAutoCreateColumnsFromModel(false);

                // Added our columns into the column model
                for (int columnIndex = 0; columnIndex < subsystemColumnHeader.length; columnIndex++){
                        // Create a column object for each column of data
                        TableColumn newColumn = new TableColumn(subsystemColumnHeader[columnIndex]);
                        subsystemTable.addColumn(newColumn);
                }

                // Put the table and header into a scrollPane
                JScrollPane subsystemScrollpane = JTable.createScrollPaneForTable(subsystemTable);
                subsystemScrollpane.setBounds(insets().left + 260,insets().top + 36,350,150);
                getContentPane().add(subsystemScrollpane);


                // Create the disk table data model

                diskTable = new JTable();

                // Added our columns into the column model
                for (int columnIndex = 0; columnIndex < diskColumnHeader.length; columnIndex++){

                getContentPane().add(diskScrollpane);

        // Add data to the table
                Vector subsystemTableData = new Vector();
                String subsystem = new String("System");
                subsystemTableData.addElement(subsystem);
                subsystemTableData.addElement("Foo");
                subsystemTableData.addElement("Bar");
            // Add a row
                subsystemTable.addRow(subsystemTableData);
                // Add a row
                subsystemTable.addRow(subsystemTableData);


        }
}
