can get a entity with entity relation to a superclass of a joined-inheritance ------------------------------------------------------------------------------ Key: EJBTHREE-722 URL: http://jira.jboss.com/jira/browse/EJBTHREE-722 Project: EJB 3.0 Issue Type: Bug Affects Versions: EJB 3.0 RC9 - FD Environment: jboss.4.0.4GA EJB 3.0 RC9-FD JDK 1.5.0_08 Reporter: Haohua xie use the ejb3 tutorial of joininheritance as the template . i did not chanage any code of Pet.java Cat.java Dog.java.i just add some functions to PetDao and PetDAOBean i write a entity, Decorate, referring to Pet. i can insert a entity of Decorate into the database but when i try to get out the entities of Decorate from the database, some exception happens. i also try the codes on jboss.4.0.4GA EJB 3.0 RC8-FD JDK 1.5.0_08. it works well and i got the result: [java] Sox [java] Junior [java] Test [java] Test2 Decorate.java package org.jboss.tutorial.joininheritance.bean;
