Fluent NHibernate mapping on multiple non-PK fields

Question

I have a situation similar to that described in Fluent NHibernate Mapping not on PK Field

However, the relationship between my tables is described by multiple non-primar

Answer 1

using hbm.xml and FluentNHibernate it is possible with a trick

class PersonMap : ClassMap
{
    public PersonMap()
    {
        Map(_ => JobTypeAndCode)
            .Columns.Add("Person_JobType", "Person_Code")
            .ReadOnly()
            .LazyLoad() // optional: prevent loading the Columns twice
            .Access.None();

        HasMany(p => p.Orders)
            .KeyColumns.Add("Person_JobType", "Person_Code")
            .PropertyRef("JobTypeAndCode")
    }

    private object JobTypeAndCode { get; set; } // FakeProperty
}

Note: i never got this to work using NHibernate MappingByCode
