Un flush supprime l'instance de l'entité ?

Décidément, je vais devenir dingue avec Hibernate ! :arf:

Encore une fois, je précise que je découvre un nouveau monde avec Seam et tout ce qui tourne avec.

En attendant d'autres informations pour résoudre ce problème, je passe à autre chose...

Dans Identifier.java, j'ai, entre autres, ceci :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

@Out(value="Nom", required=false, scope = ScopeType.SESSION) private String nom;   @Out(value="Prenom", required=false, scope = ScopeType.SESSION) private String prenom;   @Out(value="MotPasse", required=false, scope = ScopeType.CONVERSATION) private String motPasse;   public boolean identifier() { try { log.info("identification.identifier() " + "Tentative d'identification avec les paramètres suivants : " + "#{identification.nom}, #{identification.prenom}, #{identification.dateNaissance}");   // Recherche de l'étudiant Query query = entityManager.createQuery( "from ThEtudiantEtu e " + "where e.prsNom = :nom " + "and e.prsPrenom = :prenom " + "and e.etuDateNaissance = :dateNaissance "); query.setParameter("nom", this.getNom()); query.setParameter("prenom", this.getPrenom()); query.setParameter("dateNaissance", this.getDateNaissance());   ThEtudiantEtu etudiant = (ThEtudiantEtu) query.getSingleResult();   // Génération de son mot de passe log.info("identification.identifier() : affectation du mot de passe"); this.setMotPasse(etudiant.generatePassword(this.getPrenom(), this.getNom())); setAdmis(true);   setPageSuivante("/login.xhtml"); return true; }

---

Jusque là, ça fonctionne. La redirection se fait bien, les propriétés en @Out sont bien exportées et je peux les afficher sur la page de login.

Mais c'est bien beau de générer un mot de passe, encore faut-il l'injecter dans la BDD ! Alors j'ai modifié la génération du mot de passe de cette façon :

Code:

---

1 2 3 4 5 6 7

// Génération de son mot de passe log.info("identification.identifier() : affectation du mot de passe"); this.setMotPasse(etudiant.generatePassword(this.getPrenom(), this.getNom())); log.info("identification.identifier() : enregistrement du mot de passe #{identification.motPasse}"); etudiant.setUtiMotPasse(this.getMotPasse()); entityManager.flush(); log.info("identification.identifier() : mot de passe enregistré");

---

Miracle ! Ça fonctionne du premier coup ! Le mot de passe s'enregistre bien dans la table pour l'utilisateur qui vient de s'authentifier.
Mais la redirection vers la page de login plante, apparemment parce qu'il ne trouve plus le user !

Quelqu'un peut m'expliquer ce qui se passe ?

Je viens d'essayer avec :

Code:

---

entityManager.merge(etudiant);

---

Même punition ! :cry:

J'y suis arrivé en détachant la méthode generateMD5 utilisée par generatePassword de l'entité ThUtilisateurUti. Elle me posait aussi des problème dans Authenticator.java.

EDIT : J'ai parlé trop vite !

Nouveau problème sur le même sujet dans une autre discussion.

Bon, problème résolu grâce à tchize dans l'autre discussion.
