Hi Mike Minami have a one to many relationship. I'm not displaying any of the related fields in the popup. I just like the show related features option. It works great when all the foreign keys are filled in but when a foreign key is not entered in the many feature, of the one to many relationship, I get a blank popup.
1)
2) I don't need any of the related fields to show in collector. I will be interested to edit related records when that feature is available.
I've deleted my relationships and republished my feature service and the popups work again as expected.
Thanks
