If the reference is to a different table, the CRUD renders the field as a list box allowing the user to select the record in the foreign table. But as a self-join the CRUD renders the field as a simple text box and it seems to create a default value of 0 when saved. Then, I think that causes the record to generate an error when viewed ( but not when edited).
