Does the surrounding dataview (and possibly listview) have editability set to yes?
Do you have a specialization object where you have defined the access rules, but using (editing) the generalisation object in the dataview?
PS: you should consider updating to at least 7.23.19 because of a security issue in your version. ( https://docs.mendix.com/releasenotes/studio-pro/7.23#72319 )
Hi Thomas,
Looks like there is something else in your case. I just tested this scenario:
The surrounding dataview have the editability set to yes. We are on 7.23.19 there is just no 7.23.19 option when posting a question. The access rules has been set up in the module security for the entity and associated entities.
