Erreur dans un formulaire - Spring MVC
Bonjour,
J'ai une erreur au retour d'un formulaire d'une page JSP et je ne comprends pas ce qui cloche...
Au départ, j'ai un model User qui possède une référence vers une classe Authorities.

@Entity
@Table(name = "USER")
public class Users extends AbstractGenericEntity {
private static final long serialVersionUID = -8865263456343696037L;
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator="supp_seq_users")
@SequenceGenerator(name="supp_seq_users", sequenceName="SEQUENCEUSERS")
@Basic(optional = false)
@Column(name = "IDUSERS", nullable = false, precision = 22, scale = 0)
private Long idusers;
@Basic(optional = false)
@Column(name = "USERNAME", nullable = false, length = 64)
private String userName;
@Basic(optional = false)
@Column(name = "PASSWORD", nullable = false, length = 64)
private String password;
@Basic(optional = true)
@Column(name = "EMAIL", nullable = true, length = 64)
private String email;
@Basic(optional = false)
@Column(name = "ENABLED", nullable = false, length = 38)
private Boolean enabled;
@ForeignKey(name = "IDAUTHORITIESFK")
@JoinColumn(name = "IDAUTHORITIESFK", referencedColumnName = "IDAUTHORITIES", insertable=true, updatable=true)
@ManyToOne(fetch = FetchType.EAGER)
private Authorities authorities;
etc...
} |
Dans mon controller, je décide d'afficher l'état d'un user :
Code:

@RequestMapping(value="/user/addEdit.do")
public String addEdit(@RequestParam(value="id", required=false) Long id, ModelMap model) {
logger.info("UserController, edit for update a user");
Users user = null;
if (id != null) {
user = this.userService.findByIduser(id);
model.addAttribute("user", user);
return "editUser";
}
return "toto";
} |
La page JSP qui s'occupe de l'affichage, la voilà :

Donc dans cette page, il y a deux radios boutons qui permettent de choisir entre "l'authorities" ROLE_ADMIN ou ROLE_USER.
A l'affichage, pas de problème, pour un user donné, le bon radio bouton est sélectionné.
Puis, si je décide de modifier quoi que ce soit dans cette page pour retourner vers le contrôleur, j'ai de suite une erreur qui apparaît dès que j'ai appuyé
sur le bouton "submit", je ne retourne d'ailleurs jamais dans le contrôleur.
L'erreur est la suivante :

Il me dit que l'attribut "authorities" est null... Pourquoi ??
Une connaissance m'a dit que le protocole HTTP est stateless (chose que je savais) et qu'il fallait ajouter dans le form, cette instruction :
<form:hidden path="authorities" />
Chose que j'ai faite, mais j'ai tjs cette erreur...
Si quelqu'un a une idée, je suis preneur...
