I have inheritance where any(no all) of the subclass has relations one-to-one with another class, when I want to persist object of a subclass that does not have relations one-to-one( class Pendiente) says the following thing to me:

java.lang.RuntimeException: org.hibernate.PropertyNotFoundException: Unable to resolve property [name=otorgamiento] to corresponding index

my mapping is this:

<hibernate-mapping>
<class name="ar.gov.gba.spb.dpdi.modelo.rgi.cupo.EstadoCupoInvolucrado">
<id name="id" column="id" type="long" >
<generator class="foreign">
<param name="property">anterior</param>
<param name="property">otorgamiento</param>
</generator>
</id>
<joined-subclass name="ar.gov.gba.spb.dpdi.modelo.rgi.cupo.Otorgado">
<key column="id"/>
<one-to-one name="anterior" class="ar.gov.gba.spb.dpdi.modelo.rgi.cupo.RechazadoOtorgamiento" cascade="none"
outer-join="auto" constrained="false"/>
</joined-subclass>
<joined-subclass name="ar.gov.gba.spb.dpdi.modelo.rgi.cupo.Cumplimentado">
<key column="id"
/>
<one-to-one name="otorgamiento" class="ar.gov.gba.spb.dpdi.modelo.rgi.cupo.Otorgado" cascade="none" outer-join="auto"
constrained="false"/>
</joined-subclass>
<joined-subclass name="ar.gov.gba.spb.dpdi.modelo.rgi.cupo.Pendiente" >
<key column="id"/>
</joined-subclass>
</class>
</hibernate-mapping>

I thank for the answers
