I have this mapping on parent object;

<bag name="contingencies" cascade="all" inverse="true" >
<key column="riskKey"/>
<one-to-many class="Contingency"/>
</bag>

and this mapping on child:

<many-to-one name="risk" column="riskKey" class="Risk" />

When I save the parent object, the Contingency objects aren't when you add them to the parent collection. I take it this is because contingency.setRisk isn't called before save.

It would be nice to be able to set inverse="true" on the many-to-one and perhaps someone can enlighten me on why you can't do that.
