I Daniel, how alwaysUpdateModel differs from updateModel? If you have an
required form component that support some clean up logic, it can be coded
inside AjaxFormComponentUpdatingBehavior#onError, and if you need an AJAX
behavior that don't validate the form component, you can
use AjaxEventBehavior instead of AjaxFormComponentUpdatingBehavior.
The code you sent will end up invoking formComponent.valid() for non valid
components, it is problematic.
