For some reason the TableCellRenderer won't do the mouse event.
I don't get why. It works on my custom made Table Header, and sometimes you have to click twice, in order for the box to change state. That happens all the time if you change the position of the column (drag-and-drop). sometimes if you wan't to sellect a checkbox, after you click it, it will select it, but direct afterwards, even if you don't click one more time, it will deselect the checkbox (the opposite happens too).
I really don't get all these problems. Please Help.

    	public void itemStateChanged(ItemEvent e) {  e.getItem();
    		Object source = e.getSource();  
    		if (source instanceof AbstractButton == false) return;
    		boolean checked = e.getStateChange() == ItemEvent.SELECTED;

    		MyTableCellRenderer CheckBoxCellRenderer = (MyTableCellRenderer)e.getItem();
    		System.out.println(CheckBoxCellRenderer);
    		JCheckBox checkBox = (JCheckBox)(e.getSource()); 
    		JTable table = (JTable)(checkBox.getParent());
    		table.setValueAt(new Boolean(checked), CheckBoxCellRenderer.getRow(), CheckBoxCellRenderer.getColumn());
