First time user! Hope someone could point me into the right direction here.
Just recently started to use NHibernate
and I'm having problems getting the following to map correctly.
I am using mapping by code.
This is my class structure to start with
public class Entity<TPrimaryKey>
{
public virtual TPrimaryKey Id { get; protected set; }
}
public abstract class EntityParent<TPrimaryKey> : Entity<TPrimaryKey>
{
public virtual IList<EntityVersion<TPrimaryKey>> Versions { get; set; };
}
public class EntityVersion<TPrimaryKey> : Entity<TPrimaryKey>
{
public virtual EntityParent<TPrimaryKey> Parent { get; set; }
}
I have two concrete implementations of this
public class Parent : EntityParent<long>
{
public virtual string Name { get; set; }
}
public class Child : EntityVersion<long>
{
public virtual string Name { get; set; }
}
I have two separate mapping files. one for each class.
Parent
public class ParentMap: ClassMapping<Parent>
{
public ParentMap()
{
Id(x => x.Id);
Property(x => x.Name);
Bag(p => p.Versions,
map =>
{
map.Key(km => km.Column("`ParentId`"));
map.Access(Accessor.NoSetter);
map.Cascade(Cascade.Persist);
map.Inverse(true);
},
m => m.OneToMany()
);
}
}
Child
public class ChildMap: ClassMapping<Child>
{
public PaymentMethodVersionMap()
{
Id(x => x.Id);
ManyToOne(x => x.Parent, m => m.Column("`ParentId`"));
Property(x => x.Name);
}
}
When I run this I get the following exception
Result Message:
System.TypeInitializationException : The type initializer for '*****'
---- NHibernate.MappingException : Association references unmapped class:
Child[[System.Int64, mscorlib, Version=4.0.0.0, Culture=neutral,

AddCollectionSecondPass>b__12(IDictionary`2 persistentClasses)

I'm lost at what I'm doing wrong here. Can anyone point me into the right
direction? Do I really need to map the Child class separately?
