I have successfully made a "composite pattern" mapping and I use "one table".

Everything works when I have 1 baseclass, 1 composite subclass, 1 leaf subclass.

But ...

When I try to subclass the composite subclass like this ( I just show the relevant things):

<CODE>


class CompositeA : Base { ... public virtual IList<Base>Children ... }

class CompositeB : CompositeA { ... public override IList<Base> Children ... }

<MAP>

<subclass name="CompositeA" discriminator-value="A">
<list name="Children" cascade="all-delete-orphan">
<key column="ParentId"/>
<index column="ChildIndex"/>
<one-to-many class="Base"/>
</list>
</subclass>

<subclass name="CompositeB" discriminator-value="B">
</subclass>

Nhibernate does not complain in anyway and in memory everythingsfine though CASCADE does not work for Children of instances of CompositeB !!! If I explicit Save children of CompositeB instances before I put then in the list it works but that is not an option for med.

So the question HOW do I declare cascade="all-delete-orphan" for subclass CompositeB ?

If anyone know please help!

Thanks for you answer.

I did not mean "composite id" though.
