[jboss-user] [JBoss Seam] - Re: Hibernate Validation / Page Scope --> allways new entity

[mrwhite]

Ok bfo81 lets see:

My Entity Class:
package org.jboss.seam.example.client;
  | 
  | import javax.persistence.Entity;
  | 
  | import org.hibernate.validator.Length;
  | import org.hibernate.validator.NotNull;
  | 
  | @Entity
  | public class ClientPerson extends Client {
  | 	
  | 	private static final long serialVersionUID = 7829975195914473729L;
  | 	private String firstname;
  | 	private String lastname;
  | 	
  | 	@NotNull 
  | 	@Length(min=2, max=5)
  | 	public String getFirstname() {
  | 		return firstname;
  | 	}
  | 	
  | 	public void setFirstname(String firstname) {
  | 		this.firstname = firstname;
  | 	}
  | 	
  | 	@NotNull
  | 	public String getLastname() {
  | 		return lastname;
  | 	}
  | 	
  | 	public void setLastname(String lastname) {
  | 		this.lastname = lastname;
  | 	}
  | 	
  | 
  | 
  | 
  | 
  | }
  | 

My Edit Action:
package org.jboss.seam.example.client;
  | 
  | import javax.ejb.Remove;
  | import javax.ejb.Stateful;
  | import javax.ejb.Stateless;
  | import javax.persistence.EntityManager;
  | import javax.persistence.PersistenceContext;
  | 
  | import org.hibernate.validator.Valid;
  | import org.jboss.seam.ScopeType;
  | import org.jboss.seam.annotations.Begin;
  | import org.jboss.seam.annotations.Destroy;
  | import org.jboss.seam.annotations.End;
  | import org.jboss.seam.annotations.Factory;
  | import org.jboss.seam.annotations.In;
  | import org.jboss.seam.annotations.Name;
  | import org.jboss.seam.annotations.Out;
  | import org.jboss.seam.annotations.RequestParameter;
  | import org.jboss.seam.annotations.Scope;
  | 
  | @Stateful
  | @Name("clientPersonAction")
  | public class ClientPersonEditAction implements ClientPersonEdit{
  | 	
  | 	@PersistenceContext
  | 	private EntityManager em;
  | 	
  | 	@RequestParameter()
  | 	private Long clientPersonId;
  | 	
  | 	@In(required=false) 
  | 	@Out(scope=ScopeType.PAGE,required=false)
  | 	private ClientPerson newClientPerson;
  | 	
  | 	@Begin(join=true) 
  | 	@Factory("newClientPerson")
  | 	public void createNewClientPerson()
  | 	{
  | 		if(clientPersonId != null)
  | 		{
  | 			ClientPersonDAO clientPersonDAO = new ClientPersonDAO(em);
  | 			newClientPerson = clientPersonDAO.getClientPersonById(clientPersonId);
  | 			System.out.println("createNewClientPerson:" + newClientPerson.getId());
  | 		}
  | 		else
  | 		{
  | 			newClientPerson = new ClientPerson();
  | 		}
  | 	}
  | 	
  | 	@End
  | 	public String saveClientPerson() {
  | 		ClientPersonDAO clientPersonDAO = new ClientPersonDAO(em);
  | 		System.out.println("newClientPerson.getId():" + newClientPerson.getId());
  | 		clientPersonDAO.merge(newClientPerson);
  | 		return "home";
  | 	}
  | 	
  | 	@Destroy @Remove 
  | 	public void detroy()
  | 	{
  | 	}
  | 
  | 	@End
  | 	public String removeClientPerson() {
  | 		ClientPersonDAO clientPersonDAO = new ClientPersonDAO(em);
  | 		clientPersonDAO.remove(newClientPerson);
  | 		return "home";
  | 	}
  | 
  | }
  | 


My DAO Class for the Entity:
package org.jboss.seam.example.client;
  | 
  | import java.util.List;
  | 
  | import javax.persistence.EntityManager;
  | import javax.persistence.Query;
  | 
  | public class ClientPersonDAO {
  | 	
  | 	private EntityManager entityManager;
  | 	
  | 	public ClientPersonDAO()
  | 	{
  | 		
  | 	}
  | 	
  | 	public ClientPersonDAO(EntityManager entityManager)
  | 	{
  | 		this.entityManager = entityManager;
  | 	}
  | 	
  | 	public EntityManager getEntityManager() {
  | 		return entityManager;
  | 	}
  | 
  | 	public void setEntityManager(EntityManager entityManager) {
  | 		this.entityManager = entityManager;
  | 	}
  | 	
  | 	public void persist(Object obj)
  | 	{
  | 		getEntityManager().persist(obj);
  | 	}
  | 	
  | 	public void merge(Object obj)
  | 	{
  | 		getEntityManager().merge(obj);
  | 	}
  | 	
  | 	public List<ClientPerson> getAllClientPerson() {
  | 		return getEntityManager().createQuery("select c from ClientPerson c").getResultList();
  | 	}
  | 
  | 	public ClientPerson getClientPersonById(long id) {
  | 		Query q = getEntityManager().createQuery("select c from ClientPerson c where c.id = :id");
  | 		q.setParameter("id", id);
  | 		return (ClientPerson) q.getSingleResult();
  | 	}
  | 
  | 	public void remove(ClientPerson clientPerson) {
  | 		getEntityManager().remove(clientPerson);
  | 	}
  | 	
  | }
