[Java/Swing] Problema con refresh UI

[wino_7]

Purtroppo non mi fuziona così.

Ti posto il codice :

package GUI;

import EventHandler.MyMenuHandler;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import java.awt.GridLayout;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.table.DefaultTableModel;
import javax.swing.table.TableModel;

public class Assistant extends JPanel {

    private static JFrame frame;
    private static Assistant instance = null;  // E' il componente JPanel
    private JScrollPane scrollPane;
    private JTable table;
    private DefaultTableModel tableModel;

    // <editor-fold defaultstate="collapsed" desc="Costruttore : private Assistant()">
    private Assistant() {

        super(new GridLayout(1, 0));

        tableModel = new MyTableModel();
        table = new JTable();
        table.setModel(tableModel);

        // Applico l'editor e il render personalizzati
        table.getColumn("Modifica").setCellRenderer(new PanelRender());
        table.getColumn("Modifica").setCellEditor(new PanelEditor());
        table.getColumn("Cancella").setCellRenderer(new PanelRender());
        table.getColumn("Cancella").setCellEditor(new PanelEditor());
        table.setRowHeight(40); // Metto un altezza che mi consente di vedere tutto il bottone

        // Creo il pannello a scorrimento e ci inserisco la JTable
        scrollPane = new JScrollPane(table);
        add(scrollPane);
    }// </editor-fold>

    // <editor-fold defaultstate="collapsed" desc="Method : void createAndShowGUI()">
    private static void createAndShowGUI() {

        // Creazione della finestra e settaggio opzioni.
        frame = new JFrame("Assistant");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // Visualizzo JFrame con il componente JPane
