Hi Jin,

My understanding is that OJB uses a temp negative PK before insert.  does it
then lookup the db generated one and set it in  the persistent object durign
the afterStore() operation?


yep! I made some tests with PB-api and ODMG-api and it seems that when using the odmg api + SequenceManagerNativeImpl + main object with single reference, the FK set in the main object be wrong (negative value). Is this your problem too?



Haven't got any code to post right now (will follow shortly)  could there be
an issue with the cache (i.e not flushing after insert)?


normally the object will be stored to cache after the afterStore() call.

Armin


Thanks
Jin

I'm finding that the PK field with autoincrement are negative numbers -

is this normal behaviour or is somehting up?

hmm, the negative values are temporary used before the object was
written to DB.
See here

Does it cause side-effects in your environment? Could you post some
pseudo code to show the problem?

regards,
Armin
