Can't get focused a JTextField within a JTable cell

Question

I have a table and I placed a cell editor with a JText field on it for all cell editing,
I want to do things when the focus is lost or gained and my app works fine when a cell is double clicked or f2 is pressed, but when a cell is selected (without double clicking) and just begin typing it produces no focus gained event.
I tried by calling grabFocus method of that jTextField within the overriden prepareEditor method of the JTable but it doesn't get focus (doesn't even gains and loses it :s )
Does anyone have an idea of how to force this component to grab focus?
Thanks

Hai,
dont add the FocusListener to the EditorComponent.
Try to use the JTable Functions - like this:
import javax.swing.event.ChangeEvent;
import javax.swing.table.*;
import java.awt.*;
import java.awt.event.*;
import java.util.EventObject;
import javax.swing.*;
public class Test extends JFrame
     JTable table;
     JTextArea text;
     JScrollPane scroll;
     JTextField cellTextField;
     Test()
          DefaultTableModel model = new DefaultTableModel();
          cellTextField = new JTextField();
          text = new JTextArea();
          text.setEditable(false);
          scroll = new JScrollPane();
          scroll.setViewportView(text);
          table = new JTable(model){
               @Override
               public Component prepareEditor(TableCellEditor editor, int row, int column) {
                    text.append("Better use this to Start Edit!\n");
                    return super.prepareEditor(editor, row, column);
               @Override
               public void editingStopped(ChangeEvent e) {
                    text.append("Better use this to Stop Edit!\n");
                    super.editingStopped(e);
          model.addColumn("Column 1");
          model.addColumn("Column 2");          
          model.addRow(new String [] {"Cell 1", "Cell 2"});
          table.setCellSelectionEnabled( true );
          table.getColumnModel().getColumn(0).setCellEditor( new DefaultCellEditor(cellTextField));
          table.getColumnModel().getColumn(1).setCellEditor( new DefaultCellEditor(cellTextField));
          getContentPane().setLayout(new BorderLayout());
          getContentPane().add(table, BorderLayout.NORTH);
          getContentPane().add(scroll, BorderLayout.CENTER);
          setSize(300, 300);
          setVisible(true);
          setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
     public static void main(String[] args)
          new Test();
}
