Hi Jan
If you want DiscountOrder to be a child component you can get a
reference back to its parent order by using the "parent" element
inside the "component" element. Then all you have to do is have a
property to put it in and NHibernate will do the rest. I think this is
what Fabio was eluding to.
Assuming that DiscountOrder has a property of Order that is of type
IHaveDiscounts the component mapping might look like this:
<component name="DiscountOrder " class="DiscountOrder" >
<parent name="Order"/>
...
</component>
Hope that helps
