Hello Jason,

> You are probably doing something wrong.

I am not sure here, despite the fact that it is a bad idea
to have primary key column filled with "business" data.

A quick look in TIB_BDataset.DefaultDMLCacheReceivedItem shows
that for DMLCacheItemType=ditEdit InvalidateBookmark is called,
which doesn't give the expected result, when the primary key
column (used as KeyLinks) is changed.
