Still thinking on this one. The problem being, CDD's always AJAX load when the form loads, and that process automatically triggers a validation if you have AJAX validations enabled. Surprised we've never run into this before. So I'm trying to figure out the best way of flagging that this is a loading event, and don't need to validate. But that's not entirely trivial.
I'll fix it, it just might be another day or two. The code involved is fairly dense, and used by all elements, so I have to do a lot of regression testing to mae sure I don't break anything else.
