hi, when using entity inheritence with jboss 4.2.2 the EntityManager.find() call causes a org.hibernate.PropertyAccessException when called on superclass type and the subclass contains a field of primitive type. For example, i have two entities Person and Employee | @Entity | @Inheritance(strategy=InheritanceType.TABLE_PER_CLASS) | public class Person implements Serializable{ | @Id | @Column(name="ID", nullable=false) | private int id; | | @Column(name="NAME", nullable=false) | private String name; | // getter and setter..... | } | | @Entity | public class Employee extends Person implements Serializable { | | @Column(name="SSN", nullable=false) | private int ssn; | //getter and setter | | } | now after persisting a Employee a call on entityManager.find(Person.class, id) will result in a PropertyAccessException: Caused by: javax.persistence.PersistenceException: org.hibernate.PropertyAccessException: Null value was assigned to a property of primitive type setter of org.example.entity.Employee.ssn the value in the database is not null, and it worked fine with JbossAS 4.0.5 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4131628#...
