Swing Klick in Tabelle nicht möglich

[patrick_e]

Guten Tag,

ich habe eine JTable und ein Tablemodel. In der JTable befindet sich ein JButton der einen Celleditor besitzt. Wenn ich nun den JButton klicke öffnet sich ein Fenster aber ich kann nach dem schließen des Fensters nichts mehr in der JTable anklicken (Markierung funktioniert nicht mehr). Woran könnte so etwas liegen?

Celleditor

class TableCellEditor_JButton extends AbstractCellEditor implements TableCellEditor{

    JButton button;
    String txt;

    public TableCellEditor_JButton() {
        super();
        button = new JButton();
        button.setOpaque(true);
        button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                System.out.println("Buttontext: " + button.getText());
            }
        });
    }

    public Object getCellEditorValue() {
        return null;
    }

    public boolean isCellEditable(EventObject anEvent) {
        return true;
    }

    public boolean shouldSelectCell(EventObject anEvent) {
        return false;
    }

    public boolean stopCellEditing() {
        return super.stopCellEditing();
    }

    public void cancelCellEditing() {
    }

    public void addCellEditorListener(CellEditorListener l) {
    }

    public void removeCellEditorListener(CellEditorListener l) {
    }

    public Component getTableCellEditorComponent(JTable table, Object value,boolean isSelected, int row, int column) {
        txt = (value == null) ? "" : value.toString();
        button.setText(txt);
        return (JButton)value;
    }
}

Tablemodel

public class TableModel_Zuweisung implements TableModel {

    Vector<Vector> data = null;
    Vector rows = null;
    private Vector<TableModelListener> listener = null;
    Class_SQLCon sql = null;
    int kameraMode = 0;
    private static final org.apache.log4j.Logger LOG = org.apache.log4j.Logger.getLogger(TableModel_Zuweisung.class);
    JPanel_BereichZuweisung zuw= null;

    public TableModel_Zuweisung(Class_SQLCon sql, int kameraMode,JPanel_BereichZuweisung zuw) {
        this.sql = sql;
        this.kameraMode = kameraMode;
        this.zuw=zuw;
        data = new Vector<Vector>();
        rows = new Vector();
        listener = new Vector<TableModelListener>();
    }

    public void updateData(Vector v2) {

        //data.removeAllElements();
        data = v2;

        fireTableModelChanged();
    }

    @Override

        return data.size();
    }

    @Override

    @Override

                }
