Required custom properties have a warning sign to indicate that they are required, but if a user clicks "Submit" without filling one out, there is no indication that the form didn't post and why. There really needs to be some validation message to tell the user that there were required fields that were not filled out. It would also be nice if on a submit the warning sign would disappear for those fields that were filled out so that only the remaining required fields would be highlighted.

Is this fixed?
