NHibernate - Self referencing mapping interferes with foreign key mapping - nhibernate

Question

I have the following classes:
public class Track
{
public virtual int Id { get; set; }
public virtual Track MainMix { get; set; }
public virtual IEnumerable<Track> SubMixes { get; set; }
public virtual IList<FileVersion> Files { get; set; }
}
public class FileVersion
{
public virtual int Id { get; set; }
public virtual Track Track { get; set; }
}
And the following mappings:
public class TrackMap : ClassMap<Track>
{
public TrackMap()
{
Id(x=>x.Id);
References(x => x.MainMix);
HasMany(x => x.SubMixes)
.Inverse()
.Cascade.All()
.KeyColumn("MainMix_id");
HasMany(a => a.Files)
.Access.CamelCaseField(Prefix.Underscore)
.Cascade.All();
}
}
public class FileVersionMap : ClassMap<FileVersion>
{
public FileVersionMap()
{
Id(x => x.Id);
References(x => x.Track);
}
}
There is omitted code for the sake of simplicity. The Track table has a "MainMix_id" column that is a self referencing column for a parent/child relationship among Track records.
When I try to fetch a track from the database the NHProfiler tells me that Nhibernate tries to fetch the fileversions of that track with the following query:
SELECT files0_.MainMix_id as MainMix9_1_,
files0_.Id as Id1_,
files0_.Id as Id9_0_,
files0_.Track_id as Track8_9_0_
FROM [FileVersion] files0_
WHERE files0_.MainMix_id = 3 /* #p0 */
It seems like it has confused the parent id column of the Track table with its primary key column. When I remove References(x => x.MainMix) from the Track mapping the query is correct, but I don't have the parent track record returned.
Let me know if I can clarify this any more and thanks in advance for your help!

Answer 1

Does this make a difference?
TrackMap :
References(x => x.MainMix).Column("MainMix_id");
FileVersionMap :
References(x => x.Track).Column("Track_id");
