    SINGLE_TABLE strategy: problem with remoting traslation to j

    Filippo Newbie

      Jboss seam 1.0.1 GA
      JBoss 4.0.4GA (ejb3 config)
      EJB-3.0_RC8-FD

      Hello,
      my java model has 6 entity beans which inherit from a parent class where I put all the pojo stuff. I followed the single table strategy with discriminator.
      So the relational model results in a single table that contains data from all of 6 entities.
      The problem I found relates to the translation to javascript objects that Seam produces automagically. In fact in the interface javascript there is no evidence at all of the pojo stuff that belongs to the parent class. There can be eventually only specific properties and methods that belong only to the child class.
      It seems that the Seam producer inspects only one class at time, not navigating the parent object.
      As a workaround writing manually the missing objects in the interface javascript makes all the things go well.

      My parent class (fragment) is

      @Entity
      @Inheritance(strategy = InheritanceType.SINGLE_TABLE)
      @DiscriminatorColumn(name = "tipoFlag", discriminatorType = DiscriminatorType.STRING)
      @Table(name = "bo_indirizzi")
      @Name("cbi.model.bo.BoIndirizzo")
      public class BoIndirizzo implements Serializable {

      ...

      }


      One of my child classes (complete) is

      @Entity
      @Inheritance(strategy = InheritanceType.SINGLE_TABLE)
      @DiscriminatorValue(CostantiCbi.INDORDEBITORE)
      @Name("cbi.model.bo.BoOrDebitore")
      public class BoOrDebitore extends BoIndirizzo implements Serializable {
      private static final long serialVersionUID = 1L;

      }


      Did anyone experienced that?
      best regards
      Filippo
