Actionlistener for JCombobox with JCheckbox

Question

Hi!
I have written a JComboBox item which holds a checkbox :
public class CheckComboItem extends JCheckBox{
    private static final long serialVersionUID = 1677961185556377734L;
    public Integer id = 0;
    public CheckComboItem(Integer id, String text, Boolean state) {
        super(text, state);
        this.id = id;
}This works fine; However i have problems with my action listener, which should change the checkbox' selection state.
Unfortunately this only works sometimes (randomly) :-(
public class CheckComboListener implements ActionListener {
    public void actionPerformed(ActionEvent e) {
        JComboBox cb = (JComboBox) e.getSource();
        CheckComboItem store = (CheckComboItem) cb.getSelectedItem();
        store.setSelected((!store.isSelected()));
}Can you please tell me what i am doing wrong/ how this needs to be improved ?
Thank you very much!

You managed to find the Swing forum the last time you posted a Swing question.
Why didn't you search the Swing forum this time before you posted a question?
Maybe a JCheckBoxMenuItem will work better.
If you need further help then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.
