Hi

I have two tables with a parent child relationship 1:n. I'm mapping the relationship like this:

<list name="childs" cascade="all">
<key column="foreign_key"/>
<index column="order_seq"/>
<one-to-many class="mypackage.Child"/>
</list>

When I insert a child element into the list property and save the parent object I get "cannot insert NULL" into then foreign key. Shouldn't Hibernate put the value in the foreign key column???
