Thanks again.  But unfortunately the onblur Ajax called survived.

Again, I can offer a hack :D

public class DoSomeHackBehavior extends AbstractBehavior {

private static final long serialVersionUID = 3554634545756435367L;

@Override
public void onComponentTag(Component component, ComponentTag tag) {
FormComponent? comp = (FormComponent?) component;
tag.getAttributes().remove(onblur);
}
}

}

after that, you can add this behaviour to any component

component.add(new DoSomeHackBehaviour());

:D

I have found that Wicket adds an onblur Ajax call to every HTML event you
can define for the AjaxFormComponentUpdatingBehavior on a DropDownChoice
control.  I haven't tested this on other controls.  This means your server
will be getting an extra Ajax call each time a user moves focus away from
the dropdown, even if they didn't change the dropdown selection.   This
seems like a bug.

Doh!  Never mind.  I just discovered that buried in my Page was this piece of
code: AjaxFormValidatingBehavior.addToAllFormComponents(form,onblur);  
That's what was adding the onblur call to the dropdown.

I dont know if it works, but you can try to make a hack :)

endDateDropDown = new DropDownChoiceDate(endDateDropDown, new
PropertyModel(viewHistoryCriteria, endDate),
ProcessDateContext.getSixtyDayRange());
endDateDropDown.add(new AjaxFormComponentUpdatingBehavior(onchange) {
protected void onUpdate(AjaxRequestTarget target) {
if (criteriaDropDown.isEnabled()) {
populateCriteriaDropdown(target);
}
}
});
endDateDropDown.add(new AjaxFormComponentUpdatingBehavior(onblur) {
protected void onUpdate(AjaxRequestTarget target) {
// do nothing
}
});

Thanks for your reply.  I tried your suggestion, but Wicket still wrote an
Ajax call for the onblur event.  I would like to eliminate that call.
