Dear Marcus,
Thank you for your prompt reply. I am using Tapestry 4.0.2 and Honeycomb
0.3.3. For testing purpose, I have changed the configuration file as
follows.
1. Create another Hibernate Eager Load Session
<service-point id='HibernateEagerLoadSession'
interface='org.hibernate.Session'>
<invoke-factory
service-id='honeycomb.hibernate.HibernateSessionFactory' model='threaded'/>
</service-point>
2. Create Dao Service (which extends AbstractPersistenceService) that use
Hibernate EagerLoad Session
<service-point id="GenericDbDao" interface="GenericDbDao">
<invoke-factory>
<construct class="impl.GenericDbDaoImpl">
<service>HibernateEagerLoadSession</service>
</construct>
</invoke-factory>
</service-point>
3. The web project use default honeycomb hibernate session and default
honeycomb hibernate session factory.
The same errors prompt. Any suggestions?
ERROR! [Timer-0]

>15> exception in interceptor beforeTransactionCompletion()
