If you assign your primary key(s) manually, before telling Cayenne to
commitChanges(), then you'll be fine. Cayenne will honor the PK value
that you set without trying to replace it.
You didn't mention which version of Cayenne, but for version 2.0 (and
I suppose even in 3.0) you can override your data object's
setPersistenceState() method:
public void setPersistenceState(int state)
{
super.setPersistenceState(state);
if (state == PersistenceState.NEW)
{
// Initialize PK here.
}
}
For Cayenne 3.0, you can use the new lifecycle callbacks:
