I have a legacy data base and a relation one-to-one between two tables. The thing is that relation uses two columns, not one. Is there some way to say in nhibernate that when getting a referenced entity it used two columns in join statement, not one?

I'm trying to use this:

  References(x => x.Template)
            .Columns()
            .PropertyRef()

But can't get how to map join on multiple columns, any ideas?
