I have a parent class containing an listChilds object which contains List of Child elements, there is a foreign key from child table to parent table (parent_id), but Child class does not have a parent_id field, I tried with this mapping:
Code:
<class name="Parent" table="parent" lazy="false">
<component name="listChilds">
<bag name="child" cascade="all">
<key column="parent_id" not-null="true"/>
<one-to-many class="Child"/>
</bag>
</component>
</class>
<class name="Child" table="child" lazy="false">
<composite-id>
<key-property name="parent_id" column="parent_id"/>
<key-property name="field1"/>
</composite-id>
</class>
but hibernate throws the exception org.hibernate.PropertyNotFoundException: field [parent_id] not found on Child

The parent_id and field1 combination must be unique, i cannot modify any of the classes because they are generated automatically, how can i map this?
Thanks
