Hi, I'm new in hibernate... I have a problem... I'm interesting to use the event listener for notify to my class EventManager the create/update/delete on all object of my domain model. We use hibernate 3.2.5ga with spring and postgres. I have my ApplicationService under hibernateTransactionManager with AOP...and the ApplicationService send the call to persistence with Dao pattern..

Listener Configuration on SessionFactory:

Code:

<bean id="sessionFactory"      class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="annotatedClasses">
...
..my annotated class..
...
</property>
<property name="eventListeners">
      <map>
         <entry key="post-insert">
            <ref local="postInsert"/>                              
         </entry>
         <entry key="post-update">
            <ref local="postUpdate"/>                          
         </entry>
         <entry key="post-delete">
            <ref local="postDelete"/>
            </entry>         
      </map>
</property>
</bean>

<bean id="postInsert" 
   class="...my listener that implement PostInsertEventListener...">
   <property name="publisher">
         <bean class="...my class EventManager..."></bean>
   </property>
</bean>

When happened a saveOrUpdate event on my object the listener kick up, and if I try to create a new object (without save it) of the same type to entity wrapped in PostInsertEvent I'have a error. In my opinion the cause of error is when I try to query "uniqueResult".. I don't understand but hibernate try to persister the object create before (flush of session???). The stack trace of error is:

Thanks for reply.

P.S. the error only happens when the db it is empty

Error... I'm wrong...sorry... the error is on mapping wrong on my model (a unique annotation that I have forgot on Evento class variable)... this post,in my opinion, can be also remove. Thanks all.
