Since the WebObjects 5.2 uses a different table, EO_PK_TABLE instead of
EO_SEQUENCE_TABLE, for primary key generation, I need to find a way to make
the pk in sync for both 4.5.1 and 5.2 apps.

My question is how?
1. Create trigger in the database whereas whenever a update to either one
table, update the other one.
(I'm not a datatbase guy. If I create two triggers, one on EO_PK_TABLE , the
other one on EO_SEQUENCE_TABLE, will it create a infinite loop sincary?)

2. Found out where (my guess is at the control layer) the code is and modify
it such that it uses EO_SEQUENCE_TABLE.


Hi!

You if you in awakeFromInsertion set the PK yourself EOF will not do it for you.

If you there use the table you want to fetch the right PK that will work in both versions of WO.
