foreign-key

i have a collection in the mapping:

<bag name="Values" cascade="all-delete-orphan" lazy="false" inverse="true">
  <key column="[TemplateId]"/>
  <one-to-many class="MyNamespace.Value, MyLib"/>
</bag>

the Value object has a foreign key [TemplateId]. both entities has their generator set to "identity". when i call session.Save() for the parent Template object, the Value objects has their [TemplateId] (the foreign key) set to zero, so an SQL exception appears. how do i forse nhibernate to set the FK value for the child items to the value of the inserted parent object?
