Jira issue originally created by user stefanklug:

If a entity uses default values e.g.

class User {
    private $id;
    private $name = "unnamed";
}

a reference returned from EntityManager::getPartialReference() will automatically result in a scheduled update for this entity (and all fields with default values), because the EM expects the fields of the entity to be empty. This results in resetting all data inside the database to the default values when doing an $em->flush().

Regards Stefan
