Hi, i tried the following setup in my application: 2 Different UserRoles / Groups that both want to track actions. With common attributes and some different attributes. But UserRole_Spec1 should not see any actions/data from the Spec2 Group / Entity The Rights for the different entity per user role in the comment fields above them. I now wanted to create a overview Page with a list view of all action items and the different templates based on the specialisation so i can have one page for both UserRoles / Groups. But Mendix always throws an error that the UserRole_Spec1 hast no Read rights onto the Spec2_A1 attributes. What exactly is what i want. And i don`t see why this should be a error as the UserRole_Spec1 should never see any Action or Spec2 objects in that list (As there are no rights). We will have users with only UserRole_Spec1 or UserRole_Spec2 but also a few with both roles and all the flows and handling of those objects is identical. I tried to use the inheritance so i don`t need to save both into the same entity and have a bunch of empty attributes based on which type of action it is. Where is my mistake here? Anyone can explain what i understood wrong or is it not intended to use inheritance for this type of use cases?
