Fluent NHibernate and composite ID with single column name

Question

I\'ve crossed posted this in the FNH Google Group but here\'s the scoop:

I have a table in a legacy database that has a composite ID. Well, the PK is implied since t

Figured it out. You don't need to add the reference property for the parent. Notice how the many-to-one is missing in the adjusted mapping:

public AttachmentMap()
{
    SchemaIs(Resources.CityworksDatabaseSchema);
    WithTable(ObjectNames.TableWorkorderAttachment);
    UseCompositeId()
        .WithKeyReference(x => x.ParentWorkorder, "WORKORDERID")
        .WithKeyProperty(x => x.FileLocation, "IMAGEPATH");
    Map(x => x.AttachedByUser, "ATTACHEDBY").WithLengthOf(100).Nullable();
    Map(x => x.AttachedOn, "DATETIMEATTACHED").Nullable();
    Map(x => x.Comments).Nullable().WithLengthOf(256);
    //References(x => x.ParentWorkorder, "WORKORDERID").FetchType.Join();
}

This results in the following HBM mapping file. The fix is to have the composite-id have a key-many-to-one line pointing back to the parent class. Now I can persist my Attachment class.
