While starting jBpm 2.0 developments I finally find some time to implement the tip you gave me in the Amsterdam-restaurant :-)
}


4 subtypes of ActionableImpl all have this mapping :

<set name="actions" lazy="true" cascade="all">
<key column="ACTIONABLE" />
<one-to-many class="org.jbpm.model.definition.impl.ActionImpl" />
</set>

ActionImpl maps the inverse end of this relation with 'any'

<any name="actionable" id-type="long">
<column name="ACTIONABLE_TYPE"/>
<column name="ACTIONABLE"/>
</any>

The schema-export now generates a foreign-key-constraint from table Actionable to one of the 4 subtypes.

Am I missing something ? Can this be turned off ?

Thanks for your time !

Hum, I'm not familiar whith those any stuffs
Have a look at http://forum.hibernate.org/viewtopic.php?t=925949&postdays=0&postorder=asc&highlight=manytoany&start=15

I added inverse="true" to *all* set mappings like this

<set name="actions" lazy="true" cascade="all" inverse="true">
<key column="ACTIONABLE" />
<one-to-many class="org.jbpm.model.definition.impl.ActionImpl" />
</set>
