    JPA (EJB3) , javassist and polymorphism

    sducas

      Hello!


      (I don't know if this topic is related to EJB3 or Seam ManagedPersistenceContext so I post to both...

      I'm currently writing a CRUD application generator that generate a simple interface to a model Object following
      the patterns introduces by hibernate tool skeleton generator...(I'll publish it in open source very soon)

      The tool is supposed to support polymorphism but there is a problem at JPA layer when playing with polymorphism:

      I have those entities:

      - abstract Customer
      - ProCustomer extends Customer
      - SimpleCustomer extends Customer
      - Account with a customer:Customer polymorphik property


      I use the MANUAL flushing policy, with the Seam ManagedPersistenceContext.

      I search a Customer then edit it (for exemple a SimpleCustomer) then create a DailyAccount for it I sometimes have while flushing a:


      12:15:06,953 INFO [STDOUT] Hibernate: insert into Account (id, numero, solde, beneficiaire_id, gestionnaire_id, taux, plafond, DTYPE) values (null, ?, ?, ?, ?, ?, ?, 'SaveAccount')

      I can send you the whole CRUD application if you want... I'm pretty sur I'm using correctly EJB3 but it seems javassist does'nt support polymorphism does it??

      It seems there is a polymorphism issue with: javax.persistence.PersistenceException: org.hibernate.HibernateException: instance not of expected entity type: ProCustomer_$$_javassist_6 is not a: Customer...

      How can I overcome this problem ???

      THANKS!!
