流利的Nhibernate和自定义集合

我有以下Fluent NHibernate配置...

public class TemplateMap : ClassMap<Template>
{
    public TemplateMap()
    {
        Not.LazyLoad();
        Id(t => t.Id).GeneratedBy.Sequence("TEMPLATE_ID_SEQ");
        Map(t => t.Name);
        Component(t => t.Path, 
            p => p.HasMany(f => f.Fragments)
                .Access.CamelCaseField(Prefix.Underscore)
                .Cascade.AllDeleteOrphan()
                .KeyColumn("template_id")
            )
            .Access.CamelCaseField(Prefix.Underscore);
    }
}

这导致以下HBM ......

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-access="property" auto-import="true" default-cascade="none" default-lazy="true">
  <class xmlns="urn:nhibernate-mapping-2.2" lazy="false" name="TestApp.Domain.Template, TestApp, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="`Template`">
    <id name="Id" type="System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
      <column name="Id" />
      <generator class="sequence">
        <param name="sequence">TEMPLATE_ID_SEQ</param>
      </generator>
    </id>
    <component name="Path" insert="true" update="true" access="field.camelcase-underscore" optimistic-lock="true">
      <bag access="field.camelcase-underscore" cascade="all-delete-orphan" name="Fragments">
        <key>
          <column name="template_id" />
        </key>
        <one-to-many class="TestApp.Domain.Fragment, TestApp, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
      </bag>
    </component>
    <property name="Name" type="System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
      <column name="Name" />
    </property>
  </class>
</hibernate-mapping>

要将集合视为列表，我添加“AsList”方法......

public class TemplateMap : ClassMap<Template>
{
    public TemplateMap()
    {
        Not.LazyLoad();
        Id(t => t.Id).GeneratedBy.Sequence("TEMPLATE_ID_SEQ");
        Map(t => t.Name);
        Component(t => t.Path, 
            p => p.HasMany(f => f.Fragments)
                .Access.CamelCaseField(Prefix.Underscore)
                .Cascade.AllDeleteOrphan()
                .KeyColumn("template_id")
                .AsList(index => index.Column("Position"))
            )
            .Access.CamelCaseField(Prefix.Underscore);
    }
}

这导致以下HMB ......

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-access="property" auto-import="true" default-cascade="none" default-lazy="true">
  <class xmlns="urn:nhibernate-mapping-2.2" lazy="false" name="TestApp.Domain.Template, TestApp, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="`Template`">
    <id name="Id" type="System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
      <column name="Id" />
      <generator class="sequence">
        <param name="sequence">TEMPLATE_ID_SEQ</param>
      </generator>
    </id>
    <component name="Path" insert="true" update="true" access="field.camelcase-underscore" optimistic-lock="true">
      <list access="field.camelcase-underscore" cascade="all-delete-orphan" name="Fragments">
        <index>
          <column name="Position" />
        </index>
        <key>
          <column name="template_id" />
        </key>
        <one-to-many class="TestApp.Domain.Fragment, TestApp, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
      </list>
    </component>
    <property name="Name" type="System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
      <column name="Name" />
    </property>
  </class>
</hibernate-mapping>

但是，虽然第一个配置（没有“AsList”）工作正常，但第二个配置导致此运行时错误：

命名空间'urn：nhibernate-mapping-2.2'中的元素'list'在命名空间'urn：nhibernate-mapping-2.2'中具有无效的子元素'index' . 期望的可能元素列表：命名空间'urn：nhibernate-mapping-2.2'中的'meta，subselect，cache，synchronize，comment，key' .

有任何想法吗？

关于我的域模型的更多细节：模板具有id，名称和路径 . 路径是片段的有序列表 .

非常感谢
