> For example you have User and UserInfo entities. User has one-to-one relationship with
UserInfo. If you try to do select for User with prefetching on userInfo and userInfo.user,
you will get null value for userInfo property:
> SelectQuery query = new SelectQuery(User.class);
> query.addPrefetch("userInfo");
> query.addPrefetch("userInfo.user");
> It doest meter which kind of prefetching do you use.
