流利的NHibernate一对一保存

Question

我有3个类：

public class WorkEntity
{
    public virtual int WorkId { get; set; }
    public virtual OrderExtensionEntity OrderExtension { get; set; }
}
public class OrderExtensionEntity
{
    public virtual int Id { get; set; }
    public virtual WorkEntity Work { get; set; }
    public virtual IList<IssueInformation> Issues { get; set; }
}
public class IssueInformationEntity
{
    public virtual int Id { get; set; }
    public virtual long WorkId { get; set; }
}

它们被映射：

public class WorkMap : ClassMap<WorkEntity>
{
    public WorkMap()
    {
        Id(x => x.WorkId).Column("ID_ZLECENIE").GeneratedBy.Sequence("SEQ_TAE_ZLECENIE");
        HasOne(x => x.OrderExtension).Constrained();
     }
}
public class OrderExtensionMap : ClassMap<OrderExtensionEntity>
{
    public OrderExtensionMap()
    {
        LazyLoad();
        Id(x => x.Id).Column("ID_ZLECENIE").GeneratedBy.Foreign("Work");
        HasMany(x => x.IssueInformation).KeyColumn("FK_ZLECENIE");
    }
}
public class IssueInformationMap : ClassMap<IssueInformationEntity>
{
    public IssueInformationMap()
    {
       Id(x => x.Id).Column("ID_ZAD_ROZ_ADRES").GeneratedBy.Sequence("SEQ_ZAD_ROZ_ADRES");
        Map(x => x.WorkId).Column("FK_ZLECENIE").Not.Nullable();
    }
}

当我在数据库（Oracle）上创建记录时，我可以从表中获取所有信息。但我无法使用以下命令保存订单扩展实体：

var orderExtension = new OrderExtension();
orderExtension._some_variables_like_strings_to_be_saved_
Session.SaveOrUpdate(orderExtension)

如果我尝试这样做，它会告诉我"未解决的属性工作"和其他一些错误：

orderExtension.Work = new WorkEntity() { WorkId = 12345 };

试试这个映射。 这就是我的一对一关系的样子。

public class WorkMap : ClassMap<WorkEntity>
{
    public WorkMap()
    {
        Id(x => x.WorkId).Column("ID_ZLECENIE").GeneratedBy.Sequence("SEQ_TAE_ZLECENIE");
        HasOne(x => x.OrderExtension)
            .Cascade.All();
     }
}
public class OrderExtensionMap : ClassMap<OrderExtensionEntity>
{
    public OrderExtensionMap()
    {
        LazyLoad();
        Id(x => x.Id).Column("ID_ZLECENIE").GeneratedBy.Foreign("Work");
        HasOne(x => x.Work).Constrained();
        HasMany(x => x.IssueInformation).KeyColumn("FK_ZLECENIE");
    }
}
