JSpinner & FocusListener Problem

Question

Hey all....
Im trying to add a focusListener to a JSpinner so that when the spinner looses focus it saves its value in a database...
But i cant seem to get it to work, i tried to add the listener on the spinner, on the editor and on the textfield from the editor and none of them work....
what am i missing or can this be done????
thanks

ok heres the code
public class CaddyTimeField extends JSpinner implements CaddyWidget
private DataBean bean;
private boolean isDirty = false;
private CaddyPanel parent;
private int dataType;
private String propertyName;
public CaddyTimeField()
super();
init();
public CaddyTimeField(String propertyName)
super();
init();
this.propertyName = propertyName;
private void init()
Calendar cal = new GregorianCalendar(0, 0, 0, 0, 0, 0);
cal.set(Calendar.MILLISECOND, 0);
SpinnerDateModel sdm = new SpinnerDateModel(cal.getTime(), null, null, Calendar.MINUTE);
sdm.setCalendarField(Calendar.MINUTE);
this.setModel(sdm);
try
this.commitEdit();
catch (Exception e)
Trace.traceError(e);
JSpinner.DateEditor editor = new JSpinner.DateEditor(this, "HH:mm");
this.addChangeListener(new javax.swing.event.ChangeListener()
public void stateChanged(javax.swing.event.ChangeEvent e)
setDirty(true);
this.addFocusListener(new FocusListener()
public void focusGained(FocusEvent e){}
public void focusLost(FocusEvent e)
if(isDirty)
setBeanValues();
this.setEditor(editor);
private void getBeanValue()
try
Class c = bean.getClass();
Method meth = c.getMethod("get" + propertyName, null);
Object obj = meth.invoke(bean, null);
if(obj != null)
this.setValue(obj);
catch(NoSuchMethodException mex){Trace.traceError(mex);}

catch(Exception ex){Trace.traceError(ex);}
public void setBeanValues()
try

public void setBean(DataBean bean)
this.bean = bean;

public void setParent(CaddyPanel parent)
