In NHibernate how would I map an object to only retrieve it's children but ignore them when creating or updating?

Question

How would one map this object to only retrieve the collection below and ignore it totally when creating or updating the object to the db?

 <bag name="children"  table="tb_parent_child" lazy="false">
  <key column="parentID"/>
  <one-to-many class="Child"/>
</bag>

thanks

Answer 1

Why not set lazy to true? Wouldn't that basically do it? And also maybe set cascade to 'none'?

Answer 2

Setting the cascade attribute to none:

 <bag name="children"  table="tb_parent_child" lazy="false" cascade="none">
     <key column="parentID"/>
     <one-to-many class="Child"/>
 </bag>

should accomplish this. See this blog entry for a description of cascade options.
