You could override setPersistenceState() in your Treatment class:
public void setPersistenceState(int state)
{
super.setPersistenceState(state);
// If object was just created, set PK
if (state == PersistenceState.NEW)
setId(UUID.randomUUID());
}

Subject: UUID as primary key
Is there a way to set the primary key without mapping the primary key
as an object attribute?
Or is there a more elegant way of handling UUID as pk?
I have lots of tables where the pk is an UUID and the only reason why
I have to map the primary key as an object attribute is to be able to
set the pk to an UUID.
// Create object
Treatment treatment = (Treatment)
dataContext.createAndRegisterNewObject(Treatment.class);
// set pk as UUID
treatment.setId(UUID.randomUUID());
Where "setId()" is the primary key mapped as an ObjAttribute.
