I’ve done everything and double checked the data model. then i’ve done a _NewEdit popup as per lesson in chapter 3 When i add a Dropdown and i have to choose the attribute i have a white list If from that list i create a new string attribute, then it works as expected. But of courtse i must then roam and fix all other screens. Is there something i’m missing?
