Please post the stacktrace of the exact exception. In what way do you set the primarykey values, application or database ?
We set the primary key in the application.
Sometimes we create a new object with all primary keys but the row is already in the rdbms. We do this because we don't want get the object from the rdms first. Thus we have one rdbms access instead of two.
Here is the full stacktrace:
