But if you were to change the PK between that initial assignment and
saving, it would not work. That's the difference between your system
and Sibylle's: since your PK is assigned early, it appears in the
cursor's _newRecords dict. Sybylle defaults to no value, so None gets
stored in _newRecords. Later when the record is being saved, the
manually-changed PK is checked against _newRecords, and it is not
found. So Dabo treats it as an update instead of an insert, and we get
the bug that was observed.
