 Hi,
 
 How do I veto textfield inputChanged()?
 I need to prevent this from happening inside
 AjaxFormComponentUpdatingBehavior(onchange).
 
 protected void onUpdate(AjaxRequestTarget target) {
String name = getModelObject().getName();
if (query(name) == null) {
// veto value change for this field.
} else {
// refresh form
}
 }
 
 I would like to prevent any value change propagated to my domain object
 while inside ajax onchange.
 
 Thanks in advance.
 
 Cheers

Why not create a validator that does your check? You can use the
converted input prior to the model update and if. The validation
reports an error, the model is not updated
