I tried as you suggested, but I'm facing a little problem.. If I'm not
mistaken, "onError" is called on form validation, so I added my check for "no
data" in a FormValidator.. My problem is that this check needs the form
CompoundPropertyModel to be up to date with the form contents, but form
validation is called *before* the model gets updated.. Am I going the wrong
way? :/
Many thanks for your time!
