    Can you mark the nonPK attribute as PK in Cayenne (even though it is
    not), and check corresponding "toDep PK" checkbox? I suspect this is
    where the problem lies.

    Very likely the size of the target table is pure coincidence. I can't
    think of any logic in Cayenne that would depend on the table size.
