launch group operation window, you will find the table editors do not work, but on jdk1.2.2-06, they all work well.

Please see following codes:

import java.awt.*;
import java.util.*;
import javax.swing.*;
import javax.swing.table.*;
import javax.swing.event.*;
import java.awt.event.*;

public class TestJTblEditing extends JFrame
{
    public TestJTblEditing()
    {
MyTable table = new MyTable();
//table.setColumnSelectionAllowed(false);
        JScrollPane scrollPane = new JScrollPane(table);
Container c = getContentPane();
        c.setLayout(new BorderLayout());
        c.add(scrollPane, BorderLayout.CENTER);
    }

    static public void main(String[] args) {
        TestJTblEditing spTest = new TestJTblEditing();
spTest.pack();
spTest.setVisible(true);
    }
}

class MyTable extends JTable {
    public MyTable() {
        int rowCount = 3;
        String[][] data = {{"Click and Edit here"},
{"Click and Edit here"},
{"Click and Edit here"}};
        String[] columnNames = {"Editable Column"};
    
        TableModel model = new DefaultTableModel(data, columnNames) {
public boolean isCellEditable(int rowIndex, int columnIndex) {
return true;
}
        };
    
setModel(model);
    }
    
    public void editingStopped(ChangeEvent e) {
TableCellEditor editor = getCellEditor();
Object value = editor.getCellEditorValue();
setValueAt(value, editingRow, editingColumn);
System.out.println("editor on row: " + editingRow + " stopped editing");
super.editingStopped(e);
    }
}

run the class on JDk1.2 and JDK1.4, the outputed JTable.editingRow is different, on jdk1.2, it is the edited row, but on Jdk1.4, it is always -1.
in Sun Management Center, the editingRow is used. so it make SunMC running under JDK1.2 and JDK1.4 has different appearance.
