NHibernate 4.1在多对一关系中不首先插入子对象

Question

我们正尝试在应用程序中从NHibernate 3.3更新到NHibernate 4.1，以添加对新数据库系统的支持。不幸的是，与代码映射相关的行为发生了变化，我们无法找到遗漏的内容。

这两个类：

    public class Address {
    public Address( ) {
        this.Id = Guid.NewGuid( );
        this.CustomFields = new CustomFields( );
    }
    public virtual Guid Id { get; set; }
    public virtual int Version { get; set; }
    public virtual string Notes { get; set; }
    public virtual bool Deleted { get; set; }
    public virtual string Line1 { get; set; }
    public virtual string Line2 { get; set; }
    public virtual string City { get; set; }
    public virtual string State { get; set; }
    public virtual string Zip { get; set; }
    public virtual string Country { get; set; }
    public virtual ICustomFields CustomFields { get; set; }
}

public class CustomFields {
    public CustomFields( ) {
        this.Id = Guid.NewGuid( );
        this.CustomFieldDictionary = new Dictionary<string, string>( );
    }
    public virtual Guid Id { get; set; }
    public virtual int Version { get; set; }
    public virtual string Notes { get; set; }
    public virtual bool Deleted { get; set; }
    public virtual IDictionary<string, string> CustomFieldDictionary { get; set; }
}

两个映射文件如下所示：

public SQLiteCustomFieldsMap( ) {
        this.Table( "CustomFields" );
        this.Id( x => x.Id, map => map.Generator( Generators.GuidComb ) );
        this.Version( x => x.Version, map => map.Generated( VersionGeneration.Never ) );
        this.Property( x => x.Deleted );
        this.Property( x => x.Notes, attr => attr.Length( 1000000 ) );
        this.Map(
            x => x.CustomFieldDictionary,
            collectionMapping =>
            {
                collectionMapping.Table( "CustomFieldItems" );
                collectionMapping.Lazy( CollectionLazy.NoLazy );
                collectionMapping.Key(
                    k =>
                    {
                        k.Column( "CustomFieldID" );
                        k.ForeignKey( "ForeignKey_CustomFieldToDictionaryItemID" );
                    } );
            },
            mapping => mapping.Element( x => x.Column( "CustomFieldKey" ) ),
            elementRelation => elementRelation.Element(
                x =>
                {
                    x.Column( "CustomFieldData" );
                    x.Length( 1000000 );
                } ) );
    }

和：

public SQLiteAddressMap( ) {
        this.Table("Addresses" );
        this.Id( x => x.Id, map => map.Generator( Generators.GuidComb ) );
        this.Discriminator( x => x.Column("AddressType" ) );
        this.DiscriminatorValue("Address" );
        this.Version( x => x.Version, map => map.Generated( VersionGeneration.Never ) );
        this.Property( x => x.Notes, attr => attr.Length( 1000000 ) );
        this.Property( x => x.Deleted );
        this.Property( x => x.Line1, attr => attr.Length( 1000 ) );
        this.Property( x => x.Line2, attr => attr.Length( 1000 ) );
        this.Property( x => x.City, attr => attr.Length( 255 ) );
        this.Property( x => x.State, attr => attr.Length( 255 ) );
        this.Property( x => x.Zip, attr => attr.Length( 25 ) );
        this.Property( x => x.Country, attr => attr.Length( 255 ) );
        this.ManyToOne(
            x => x.CustomFields,
            attr =>
            {
                attr.Class( typeof(CustomFields) );
                attr.ForeignKey( "ForeignKey_AddressToCustomFieldsID" );
                attr.Cascade( Cascade.Persist );
            } );
    }

以下是产生问题的电话：

this._address = new Address
                            {
                                Notes = "Notes",
                                Line1 = "Line 1",
                                Line2 = "Line 2",
                                City = "City",
                                State = "State",
                                Zip = "Zip",
                                Country = "Country",
                                CustomFields = new CustomFields { CustomFieldDictionary = new Dictionary<string, string> { { "Key 1", "Data 1" } } }
                            };
            this.Session.Save( this._address );

在检查日志之后，似乎正在发生的事情是在NHibernate 3.3中，＆＃39; CustomField＆＃39;首先插入对象，然后输入＆＃39;地址＆＃39;对象，然后是＆＃39; CustomFieldItems＆＃39;对象。在NHibernate 4.1中，它试图插入地址＆＃39;对象优先，它没有通过外键检查，结果测试失败。

谷歌在Stack Overflow上搜索并没有帮助，所以我们现在寻求帮助！我能得到的最接近的是我们必须在ManyToOne（）关系中添加一些新属性或更改现有属性，但不确定需要采用哪种方式。感谢所有能帮助我们指明正确方向的人。
