I think you mave have failed to instantiate an instance of Person inside EntityHome. @Name("personHome") | public class PersonHome extends EntityHome<Person> { | | private static final long serialVersionUID = 219059304048820709L; | | public void setPersonId(Long id) | { | setId(id); | } | | public Long getPersonId() | { | return (Long) getId(); | } | | @Override | protected Person createInstance() | { | Person person = new Person(); | return person; | } | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4041185#...
