The specification has:
/**
* Return the id of the entity.
* A generated id is not guaranteed to be available until after * the database
insert has occurred.
* Returns null if the entity does not yet have an id.
* @param entity entity instance
* @return id of the entity
* @throws IllegalArgumentException if the
* to be an entity
*/
public Object getIdentifier(Object entity);
So, the only time it's supposed to return null is when the entity does not have
an id. Am I reading that correctly?
