NHibernate бросает и исключает, когда пытаюсь удалить объект, у которого есть многозначный составной ключ. Сохранение объекта работает правильно. Вот исключение:NHibernate KeyNotFoundException при удалении
[KeyNotFoundException: The given key was not present in the dictionary.]

Вот что мой домен выглядит следующим образом:
public class Order : EntityBase {
protected Order() {}
public Order(Guid persistenceId) : base(persistenceId) {
this.Lines = new List<OrderLine>();
}
public virtual int OrderId {get; private set;}
IList<OrderLine> Lines {get; private set;}
}
public class OrderLine : EntityBase {
protected OrderLine() {}
public OrderLine(Guid persistenceId, Order order, int lineId) : base(persistenceId) {
this.Order = order;
this.LineId = lineId;
}
public virtual Order {get; private set;}
public virtual LineId {get; private set;}
}
public abstart class EntityBase {
protected EntityBase() {}
protected EntityBase(Guid persistenceId) {
this.PersistenceId = persistenceId;
}
public virtual Guid Persistenceid {get; private set;}
public bool IsTransient {get {return Equals(this.PersistenceId, default(Guid)); }}
public override bool Equals(object obj) {
if(ReferenceEquals(null, obj))
return false;
if(ReferenceEquals(this, obj))
return true;
if(this.GetType() != obj.GetType())
return false;
return this.Equals((IEntity)obj);
}
public virtual bool Equals(IEntity other) {
if(ReferenceEquals(null, other))
return false;
if(ReferenceEquals(this, other))
return true;
if(this.IsTransient || other.IsTransient)
return false;
return this.PersistenceId.Equals(other.PersistenceId);
}
public override int GetHashCode() {
return this.IsTransient ? base.GetHashCode() : this.PersistenceId.GetHashCode();
}
}
Вот что мои картографические файлы выглядеть следующим образом:
public class OrderClassMap : ClassMap<Order> {
public OrderClassMap() {
this.Table("Orders");
this.Id(x => x.OrderId).Generated.Identity();
this.Map(x => x.PersistenceId);
this.HasMany(x => x.Lines).Inverse().KeyColumn("OrderId").Cascade.AllDeleteOrphan();
}
}
public class OrderLineClassMap : ClassMap<OrderLine> {
public OrderLineClassMap() {
this.Table("OrderLines");
this.CompositeId()
.KeyReference(x => x.Order, "OrderId")
.KeyProperty(x => x.LineId);
this.Map(x => x.PersistenceId);
}
}
