NHibernate.MappingException: Could not determine type for: Id column

[Dietrich]

I'm on my first project using Conformist by-code mapping, and I hit a snag.

Basically, I've got this class

public class SOPProcess : ISOPProcess
	{
		public virtual Guid Id { get; set; }

                [...]

        }

And I'm using this mapping 

	public SOPProcessMap()
	{
		Id(s => s.Id, i => i.Generator(Generators.GuidComb));
                [...]
        }

And I'm getting this error:

NHibernate.MappingException: Could not determine type for: MES.ProcessManager.SOP.SOPProcess, MES.ProcessManager, for columns: NHibernate.Mapping.Column(id)

And now I'm scratching my head. 

What did I miss? 

I've posted this on stackoverflow as well

I had this problem too, but it doesn't have to do with the mapping of your primary key.

Do you have a one to many mapping from another class?

Yes, the SOP object maps it, as so.

Set(s => s.Processes, m =>

	   {
		m.Table("SOPProcess");
		m.Cascade(Cascade.DeleteOrphans);
		m.Fetch(CollectionFetchMode.Subselect);
		   m.Key(k =>
		     {
			k.Column("SopId");
			k.ForeignKey("FK_SOPProcess_SOP");
	             });
         });

I've had trouble finding solid documentation on this stuff, so please point out my dumb mistakes.

I ran across the same problems.

You haven't defined the type of relationship. See the line action => action.OneToMany()); in the mapping below.

public class SportMap : ClassMapping<Sport>
{
public SportMap()
{
Id(x => x.Id, map =>
{
map.Column("Id");
map.Generator(Generators.GuidComb);
});

Property(x => x.Name, map =>
{
map.NotNullable(true);
map.Length(50);
});

Bag(x => x.Positions, map =>
{
map.Key(k => k.Column(col => col.Name("SportId")));
map.Cascade(Cascade.All | Cascade.DeleteOrphans);
},
action => action.OneToMany());

Property(x => x.CreateDate);
Property(x => x.CreateUser);
Property(x => x.LastUpdateDate);
Property(x => x.LastUpdateUser);

}
}

Adding the action map to all of the Set mappings got me past that error, thanks. Why is that not a requirement in the mapping?

Because yo may have an event-handler or a custom IModelInspector managing the situation.

For example have a look to the code of the ConventionModelMapper
