Hi, I've some problems with nested inheritance :

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
<class name="BaseClass" table="...">
<joined-subclass name="ClassA" table="....">
...
</joined-subclass>
<joined-subclass name="BaseClassB" table="...">
<discriminator column="..." type="System.String" />
<subclass discriminator-value="Value1" name="ClassB_1">
</subclass>
</joined-subclass>
</class>
</hibernate-mapping>

But when I try to add the mapping file the compiler throws an exception because the subclass it's not supported inside a joined-subclass node...

Thanks

Combination of joined-subclass and subclass inheritance strategies isn't supported in Hibernate prior to Hibernate 3.0 (NHib is a port of Hib 2.x).

So this can't be done currently. The NHib port of Hib 3.0 is underway I believe (and they have been kcking butt lately).

Thanks for your reply :)

Happy to help
