Hi!
Are you doing anything with relationships? That happened to me
when I modeled some relationships in the wrong way.
Also, have you installed both PSQL plugins (the framework, and the
one for Modeler) and generated the SQL in the Modeler correctly?
Yours

Hi list,
I'm running accross a strange problem: when inserting multiple
objects of the same class to the DB, I get the following exception:
SQL State:23505 -- error code: 0 -- msg: ERROR: duplicate key
violates unique constraint moduleinmodule_pk
When inserting one object at time, it works great.
Example in less-than-pseudo-code:
Create instance of object
Insert object to editing context
Modify object
Create other instance of the same class
Insert to EC
Modify object
EC.saveChanges()
= crash
Create instance of object
Insert object to editing context
Modify object
EC.saveChanges()
= it works
The EOModel is properly configured, the primary key is not editable
It happens only with objects of this class ('moduleinmodule')
Configuration: WO 5.3.1, PostgreSQL 8.0.1
Do you have any pointers?
Regards,
François ___
