I have noticed that when modifying lookup records in an editable grid, inside a model driven app, the drop down tab that appears will show either no options or the names of existing records. It does not show the options actually stored in the lookup column.
The operation of lookup columns works correctly, when modifying the columns displayed using the "edit columns" button in the top right corner, and finally saving this as a new view.
Essentially, lookup columns do not work as expected in non-saved views, whether default or custom.
Is this expected behavior?
