I had the same problem with you before, and now I found that if you set the
cache type to be "none", it then works fine.
What's the default cache type if not specified for the class?
I think it should be a bug, because when I don't use lazy loading, I can get
the correct relationship even I don't specify the cache type either.
Do you think so?
Thanks,
John W
