This definition used to work. The backing data object would throw an exception and I could catch it with the ValidationErrorTemplate. Now VS2010 breaks on the exception in the business class and then it goes to our unhandled exception handler. It's been a while since I actually checked this, so it may not have anything at all to do with you. We are using 10.2.532.
Thanks.
Thanks.
