NHibernate的许多一对多袋的关联表

我知道这已被要求，并回答了很多次不插入，但我有两个类多到很多。我已经用袋子来互相映射它们。这里是NHibernate的映射：NHibernate的许多一对多袋的关联表

日历：

<?xml version="1.0" encoding="utf-8"?>

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">

    </id> 
    <property name="Name" length="100" />

CalendarEvent：

<?xml version="1.0" encoding="utf-8"?> 
<!--Generated by NHibernate.Mapping.Attributes on 2009-10-09 18:27:46Z.--> 
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> 
    <class name="Calendar.CalendarEvent, Calendar" table="CalendarEvents"> 
    <id name="CalendarEventId" column="CalendarEventId" type="Int32">

    <property name="Address1" length="255" /> 
    <property name="Address2" length="255" />

    <property name="Zip" length="10" /> 
    <property name="Title" length="255" /> 
    <property name="Url" length="255" /> 
    <property name="ExternalSystemId" /> 
    <property name="ExternalSystem" type="Calendar.GenericEnumMapper`1[[Calendar.ExternalSystemType, Calendar, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], Calendar" length="50" /> 
    <property name="RecordCreatedBy" column="CreatedBy" length="50" /> 
    <property name="RecordModifiedBy" column="ModifiedBy" length="50" /> 
    <property name="CreateDate" /> 
    <property name="ModifiedDate" /> 
    <many-to-one name="ParentEvent" column="ParentEventId" /> 
    <bag name="ChildEvents" lazy="true" fetch="subselect" cascade="all" inverse="true"> 
     <key column="ParentEventId" /> 
     <one-to-many class="Calendar.CalendarEvent, Calendar" /> 
    </bag> 
    <bag name="Calendars" table="CalendarEventsInCalendar" lazy="false" inverse="true"> 
     <key column="CalendarEventId" /> 
     <many-to-many class="Calendar.Calendar, Calendar" column="CalendarId" /> 
    </bag> 
    </class> 
</hibernate-mapping>

这里就是我如何添加事件到日历：

public virtual void AddEvent(CalendarEvent calEvent) 
    { 
     if(!calEvent.Calendars.Contains(this)) 
      calEvent.Calendars.Add(this); 

     Events.Add(calEvent); 
    }

然后我做了SaveOrUpdate（日历）

有什么想法？
