----------------------------------------------------------

                 Key: CAY-1695
                 URL: https://issues.apache.org/jira/browse/CAY-1695
             Project: Cayenne
          Issue Type: Bug
          Components: Core Library
    Affects Versions: 3.1M3
            Reporter: Andrei Veprev


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.
