FK to non-PK relationship

["V.B. Skrypnyk" <va...@skrypnyk.net>]

I saw posts on the following subject, but didn't see any replies:

If a persistent class A has a reference to a persistent class B, can the
foreign key in class B point to a field that is NOT the primary key in class
A? If my understanding is correct it's impossible to do right now, at least
I can't see a way to declare such a relationship in the repository (I
concede that such situations shouldn't occur, but consider legacy data).

Anyway, I thought that perhaps as a quick fix, the concept of
QueryCustomizer can be extended to reference-descriptors as well. This way
the user can programmatically adjust the query and set the related fields.

Cheers,
