Problem with multiple ModalPopupExtenders in the same page, each requiring validation. For some reason I'm not seeing, the validation on the second fires (i.e., the error message displays), but the postback is not canceled and further, Page.IsValid is true in the code-behind. On the first MPE, the postback is canceled and we never hit the code-behind.
Markup for the modals:
