Hi,

I’m using NHibernate 2.1.0.4 and VB.NET with Oracle.

Is it possible to have a one-to-many relation to a class that has a composite key being able to provide only one key property of the composite key?

In my case:

Code:

<class name=" Component " table="Component" >

    <composite-id name="CompositeId" class="CompositeId">
      <key-property name="ComponentTypeId" column="ComponentTypeId"/>
      <key-property name="ComponentId" column="ComponentId"/>
    </composite-id>
        
</class>

I have then the Policy class that has a one-to-many relation with the Component class but can only provide the ComponentId property.

Is there a way to set the ComponentTypeId maybe through a SQL query?

Thanks in advance!
