Issue with JButton clicking

Question

Hi guys,
I'm having an issue with a JTable, I hope you can help me.
Last cells of each row is a JButton and my issue is with click on that button.
In fact, it's required clicking two times to run code linked to listener for the same button.
What I need is clicking just one time to run code, not two times.
This is code to build Table:
private JTable getJTable() {
          if (jTable == null) {
               jTable = new JTable();
               jTable.setModel(new MyTableModel());
               final MyTableModel tabella = (MyTableModel) jTable.getModel();
               Vector<String> nameColumn = new Vector<String>();
               nameColumn.addElement("Cliente");
               nameColumn.addElement("Data");
               nameColumn.addElement("Esito");
               nameColumn.addElement("Immagine");
               nameColumn.addElement("Dettagli");
               tabella.setColumnIdentifiers(nameColumn);
               tabella.setElencoDiagnosi(true);
               final Vector<Diagnosi> elencoDiagnosi = gestioneDiagnosi.selectAllDiagnosi();
               jTable.getColumn("Dettagli").setCellRenderer(new PanelRender());
             jTable.getColumn("Dettagli").setCellEditor(new PanelEditor());
             jTable.getColumn("Immagine").setCellRenderer(new PanelRender());
             jTable.getColumn("Immagine").setCellEditor(new PanelEditor());
             jTable.setRowHeight(36); //Metto un altezza che mi consenta di vedere tutto il bottone
             JButton[] arrayButtonDettagli = new JButton[elencoDiagnosi.size()];
             JButton[] arrayButtonImmagini = new JButton[elencoDiagnosi.size()];
             for (int i=0;i<elencoDiagnosi.size(); i++)
                  final int contatore=i;
                  arrayButtonDettagli[i] = new JButton("Elenco Dettagli");
                  arrayButtonDettagli.addActionListener(new ActionListener() {
                         public void actionPerformed(ActionEvent e)
                              Diagnosi diagnosi=elencoDiagnosi.get(contatore);
                              GUIElencoDiagnosi.this.dispose();
                              GUIModificaDiagnosi modificaDiagnosi =
                                   new GUIModificaDiagnosi(OrthoLabMain.listaUtenti,
                                        risultati,diagnosi);
                              modificaDiagnosi.setVisible(true);
          final Diagnosi diagnosi=elencoDiagnosi.get(i);
          arrayButtonImmagini[i] = new JButton(new javax.swing.ImageIcon(getClass().getResource("/image/jpg-icon.gif"))) ;
          arrayButtonImmagini[i].setSize(36, 36);
          arrayButtonImmagini[i].setBackground(Color.WHITE);
          arrayButtonImmagini[i].addActionListener(new ActionListener() {
                         public void actionPerformed(ActionEvent e)
                              JOptionPane.showMessageDialog(null,"","Zoom Immagine",
                                        JOptionPane.INFORMATION_MESSAGE,new ImageIcon(diagnosi.getImmagine()));
          Object[] row = new String[4];
          row[0]=diagnosi.getCognomeCliente()+" "+diagnosi.getNomeCliente();
          String dataviewanno=diagnosi.getData().substring(0, 4);
          String dataviewmese=diagnosi.getData().substring(4,6);
          String dataviewgiorno=diagnosi.getData().substring(6, 8);
          row[1]=dataviewgiorno+"/"+dataviewmese+"/"+dataviewanno;
          row[2]=diagnosi.getEsito();
          tabella.addRow(row);
          tabella.setValueAt(arrayButtonImmagini[i],i, 3);
                    tabella.setValueAt(arrayButtonDettagli[i], i, 4);
          return jTable;
This is code for CellRender and CellEditor (written ad hoc)Cell renderer (PanelRenderer)
public class PanelRender extends DefaultTableCellRenderer {
     private static final long serialVersionUID = 1L;
     public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
if(value instanceof JComponent) {
return (JComponent)value;
} else {
return super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
Cell Editor (PanelEditor)
public class PanelEditor extends AbstractCellEditor implements TableCellEditor {
     private static final long serialVersionUID = 1L;
     private JComponent panel = null;     
     public Object getCellEditorValue() {
          return panel;
     public Component getTableCellEditorComponent(JTable table, Object value,
               boolean isSelected, int row, int column) {
          panel = (JComponent)value;
          return panel;
Could you help me?

Answer 1

Thanks Ryan,
I solved my issue with your help. Now I've a bit issue, that is I can't see icon on my button, it seems like toString method is displayed instead icon.
For table renderer I use a new class that implements TableCellRenderer, while for model I use a new class that extends DefaultTableModel.. In the following some code...please help me, icon on button aren't shown! Thanks
private JScrollPane getJScrollPane(Vector<Diagnosi> ris) {
          if (jScrollPane == null) {
               TableCellRenderer defaultRenderer;
final MyTableModel tabella = (MyTableModel) jTable.getModel();
               defaultRenderer = jTable.getDefaultRenderer(JButton.class);
               jTable.setDefaultRenderer(JButton.class,
                           new PanelRender(defaultRenderer));
               jTable.getColumn("Immagine").setCellRenderer(defaultRenderer);
               jTable.getColumn("Immagine").setCellEditor(new PanelEditor());
               jTable.getColumn("Regolo").setCellRenderer(defaultRenderer);
               jTable.getColumn("Regolo").setCellEditor(new PanelEditor());
               jTable.getColumn("PDF").setCellRenderer(defaultRenderer);
               jTable.getColumn("PDF").setCellEditor(new PanelEditor());
               jScrollPane.setViewportView(jTable);
          return jScrollPane;My Table Model
public class MyTableModel extends DefaultTableModel {
          public MyTableModel(Object[][] data, Object[] columnNames) {
             super(data, columnNames);
          public MyTableModel(){
               super();
          public boolean isCellEditable(int row, int column) {
               if(elencoClienti){
                    if(column!=5)
                         return false;  
                    else return true;
               else if(elencoDiagnosi){
                    if(column<3)
                         return false;
                    else return true;
               else if(clientiLista)
                    return false;
               else if(diagnosiLista){
                    if(column<3)
                         return false;  
                    else return true;
               else if(clientiPerDiagnosi){
                    if(column!=3)
                         return false;
                    else return true;
               else return false;
     }Panel Editor
public class PanelEditor extends AbstractCellEditor implements TableCellEditor {
     private static final long serialVersionUID = 1L;
     private JComponent panel = null;     
     public Object getCellEditorValue() {
          return panel;
     public Component getTableCellEditorComponent(JTable table, Object value,
               boolean isSelected, int row, int column) {
          panel = (JComponent)value;
          return panel;
}
