it would be helpful if I didn't post before I was done.
Now, I was attempting to load a unique Child given a Parent's Id.
Something like:
var query = Session.CreateQuery("from Child child where
child.Parent.Id=:parentId");
query.SetInt32("parentId", _parentId);
return query.UniqueResult<Child>() as Child;
I ended up getting the "Creating proxy instance failed." error
message.
Is this because there is no way to guarantee uniqueness since I'm not
supplying enough criteria to uniquely select a Child?
Or does it not make sense to instantiate the child side of a many to
many association on its own?
Hopefully this isn't an ignorant question.
