Hello,

I'm trying to map the following XML. It seems that i can't use <generator class="identity"> in the super class. How can i solve this mess ???

Thanks!!!

(using microsoft sql server db)

The exception:

Caused by: org.hibernate.MappingException: Cannot use identity column key generation with <union-subclass> mapping for: clientes.Empresa
----------------------------------------------------------------

The mapping:


<class name="clientes.UsrCliente">

<id name="id">
<generator class="identity"/>
</id>

<property name="Activo" column="Activo" not-null="true" type="boolean"/>
<property name="Comentarios" column="Comentarios" not-null="false" length="400" type="string"/>
<property name="Direccion" column="Direccion" not-null="true" length="200" type="string"/>

<property name="Fax" column="Fax" not-null="false" length="20" type="string"/>
<property name="Telefono" column="Telefono" not-null="true" length="20" type="string"/>

<union-subclass name="clientes.Empresa" table="Empresas">
<property name="Denominacion" column="Denominacion" not-null="true" length="100" type="string"/>
