Hi all

I have this error
org.hibernate.type.SerializationException: could not deserialize

My .hbm.xml file is

<class name="Permission" catalog="prisaseguridad" table="per_permission">
<composite-id>
<key-property name="application" column="per_application_id" type="com.prisacom.se.security.model.Application"/>
<key-property name="object" column="per_esobject_id" type="com.prisacom.se.security.model.ESObject"/>
<key-property name="field" column="per_esfield_id" type="com.prisacom.se.security.model.ESField"/>
<key-property name="type" column="per_type_id" type="com.prisacom.se.security.model.PermissionType"/>
<key-property name="media" column="per_media_id" type="com.prisacom.se.security.model.Media"/>
<key-property name="user" column="per_user_id" type="com.prisacom.se.security.model.User"/>
<key-property name="group" column="per_group_id" type="com.prisacom.se.security.model.Group"/>
<!-- <key-property name="relationship" column="per_media_id" type="com.prisacom.se.security.model.Media"/> -->
</composite-id>
<property name="enabled" column="per_enabled"/>
</class>

and my HSQ is

Session session = getSessionFactory().getCurrentSession();
Transaction tx = session.beginTransaction();
//ESElement var = (ESElement) filter;
//session.get(var.getClass(),var.getId());
result = session.createCriteria(filter.getClass().getName()).
add(Example.create(filter).ignoreCase().
enableLike(MatchMode.ANYWHERE)).list();
tx.commit();

I have read this problem can be because of wrong mapping using <property> tags. How can I resolve it? Any idea?

Thanks in advance
