Suppose I had the following resources:

Quote:

A.hbm.xml

Code:

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
   <class name="A, Date" table="A" lazy="false">
      <id name="ID" column="ID" type="Int32" unsaved-value="0">
         <generator class="native"/>
      </id>
      <set name="Bs" lazy="true" cascade="save-update" inverse="true">
         <key column="AID"/>
         <one-to-many class="B, Date"/>
      </set>
   </class>
</hibernate-mapping>

Quote:

B.hbm.xml

Code:

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
   <class name="B, Date" table="B" lazy="false">
      <composite-id>
         <key-many-to-one name="A" column="AID" class="A, Date"/>
         <key-property name="FromTime" column="`from`" type="DateTime"/>
      </composite-id>
   </class>
</hibernate-mapping>

After I save both a and b. Only a can be saved, I turn on the "show_sql" and I cannot find any insert statement to saving b object. Did I get any wrong?

Try adding insert=true update=true to this line

<set name="Bs" lazy="true" cascade="save-update" inverse="true">

If you provide the code you used to test these objects we may be able to provide additional assistance. Maybe there is a reason why nhibernate is not saving B. Maybe it was being saved as part of an earlier process, and we are just missing it. Please provide an entire test that shows the issue.

Seems insert is not a valid of the nhib 1.2 schema:
NHibernate.MappingException: The 'insert' attribute is not declared. ---> System

.Xml.Schema.XmlSchemaException: The 'insert' attribute is not declared.

at NHibernate.Cfg.Configuration.ValidationHandler(Object o, ValidationEventAr

gs args)

at System.Xml.Schema.BaseValidator.SendValidationEvent(XmlSchemaException e,

XmlSeverityType severity)

at System.Xml.Schema.XsdValidator.ValidateStartElement()

at System.Xml.Schema.XsdValidator.ProcessElement(Object particle)
