I suppose you do have RequestLive true?

If so, it seems as though your KeyLinks are not able to uniquely identify
an underlying row in the table you marked as KeyRelation. Have you got an
outer join there, with nulls falling into the Keylinks? Do you have enough
elements in your KeyLinks to ensure uniqueness?

Show your SQL, KeyLinks and KeyRelation.
