Does the object you are trying to load over association exist?
Or is the object AttachedDocument a new object?
In that case the dataview is not editable and you have to creat an object.
For example in the DataView with as datasource a microflow.
Hope this helps!
Thanks for your answer. Indeed, the object does not exist. According to your suggestion, I created an object in a microflow and passed it on to a new page I created. Unfortunately I end up in the same situation.
I attached four screenshots .
Forum1.png with the properties of the list view.
Forum2.png with the properties of the data view.
Forum3.png with the microflow, which is triggered by the Add button.
Forum4.png with the relevant area of the datamodel.
Thanks for your assistance.
