The board administrator has requested that you must provide some message content within your post. You cannot post only HTML, Images, EmotIcons or IFCode. My post was just text, and I tried it a few times. Anyone else having issues?
You had some formatting that wasn't supported. If you paste the text into NotePad or something the copy it from there it will strip the formatting and you will be able to paste it without being scolded
Am I correct that DDT does not support constraints currently?
No. The DDT does support contraints. They are created for you when you create a relationship or setup a default value.
Obviously you can call script like you have done to do this for you. But the DDT will create all of the contraints for you if you setup your relationships. Also, when you assign a default value to a field, a constraint will be created as well.
