I'm trying to implement a Value Change Listener with my Managed Bean.  It looks pretty simple, but I keep having errors.

 

Here is the test method in my bean: 

 

public void processValueChange(ValueChangeEvent event) throws AbortProcessingException {

String id = event.getComponent().getId();

String oldVal = event.getOldValue().toString();

String newVal = event.getNewValue().toString();

System.out.println("Component:" + id + " value changed from " + oldVal + " to " + newVal);

}

 

I'm binding it to the Edit Control with the valueChangeListener property, myBean.processValueChange 

 

I'm getting an very unhelpful error message below on the server  

 

myBean.processValueChange(javax.faces.event.ValueChangeEvent) com.sun.faces.lifecycle.ProcessValidationsPhase

2011-07-15T14:27:05.628-04:00 SEVERE CLFAD0134E: Exception processing XPage request  

2011-07-15T14:43:37.368-04:00 SEVERE processValueChange: myBean.processValueChange(javax.faces.event.ValueChangeEvent) com.sun.faces.lifecycle.ProcessValidationsPhase 

 

 Has anyone implemented ValueChangeListener with a managed Bean

 

Any help is always appreciated. 

 

Thanks,
