Hibernate version:
3.0 release
Mapping documents:

Code:

<hibernate-mapping package="com.llic.calc.variable">
  <joined-subclass name="DatabaseVariable" table="DatabaseVariable" extends="Variable">
  
   <key column="variableId"/>
         
   <property name="className" column="className" type="string"/>
   
   <property name="property" column="property" type="string"/>
   
   <bag name="parameters" table="objectProperties" cascade="all" lazy="false">

   <many-to-one name="hibParam" class="com.llic.ides.dao.impl.HibParameter" cascade="all" lazy="false"/>
  
    
  </joined-subclass> 
</hibernate-mapping>

Code:

<hibernate-mapping package="com.llic.ides.dao.impl">

  </class> 
</hibernate-mapping>

Code between sessionFactory.openSession() and session.close():
session.merge(obj); //where obj is an instance of idesdata

Full stack trace of any exception that occurs:
None

Name and version of the database you are using:
MySQL 4.0

When my usertype is called for the object "value" then the value of the object in every call is null. Using the debugger, I can clearly see that the "entity.value" object is an instanciated java.util.Date object. It appears that the call to persister.getPropertyValues(entity, source.getEntityMode()) on line 230 of DefaultMergeEventListener is returning a null for the "value" field in the Object array. How can I get around this? I have a few other custom persisters that are working fine, this really has me stumped....

Dissable "optimizer" in configuration properties, it will help to debug.

I have set the cglib optimizer property to false, but hibernate appears to still use cglib, not using the reflection mechanism. The property I added to my config is...

Code:

<property name="hibernate.cglib.use_reflection_optimizer">false</property>

In the PojoTupilizer class line 182, It is still calling getPropertyValuesWithOptimizer(entity);

Code:

public Object[] getPropertyValues(Object entity) throws HibernateException {
      if ( shouldGetAllProperties( entity ) && optimizer != null ) {
         return getPropertyValuesWithOptimizer( entity );
      }
      else {
         return super.getPropertyValues( entity );
      }
   }

Any ideas?

this is a system level property (as per the doc) you need to set it in the .properties or through a -D option

It does not work programmatically also

Code:

configuration.setProperty("hibernate.cglib.use_reflection_optimizer", "false")
