Can i use List Collections in joined-subclasses ?
Something like:

<joined-subclass name="Products.Product" table="T_Product">
<key column="P_IdProduct"/>
<many-to-one name="organizacion" class="Common.Organizacion" column="F_IdOrganizacion"/>
<list name="suplementos" lazy="false" cascade="all" inverse="true">
<key column="P_IdSuplement"/>
<one-to-many class="Products.Product"/>
</listt>
</joined-subclass>

Hibernate throws the following Exception
18:15:48,668 INFO Configuration:300 - Mapping resource: Productos/ElementoEditorial.hbm.xml
18:15:48,758 ERROR XMLHelper:48 - Error parsing XML: XML InputStream(18) Element "list" does not allow "one-to-many" here.
18:15:48,788 ERROR XMLHelper:48 - Error parsing XML: XML InputStream(19) Element "list" requires additional elements.
18:15:48,788 INFO Binder:225 - Mapping class: Productos.ElementoEditorial -> T_ElementoEditorial

Yep, I use lists in joined-subclasses all over the place.

First, you need an index.

From the DTD:

Code:

<!ELEMENT list (
   meta*,
   (cache|jcs-cache)?,
   key, 
   index, 
   (element|one-to-many|many-to-many|composite-element|many-to-any)
)>

Also the ending tag "</listt>" will mess you up too. :)
