bonjour,

Je souahite afficher Dans une liste deux groupes. Par exemple ma liste pourrait etre :
Utilisateurs
user 1
user 2
Group
group 1
group 2

Lorsque j'exécute mon code j'ai une erreur que je n'arrive pas a résoudre.: java.lang.NumberFormatException

Voici ma page JSP:

                            </span>

Merci pour votre aide

[Sniper37]

à priori,

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

PREFIX_USERS + changedUser.getId()

n'est pas un String?

utilise un converter sinon.

[Edta]

C'est un String. Quand j'affiche le label de l'option dans la boucle il n'y a pas de probleme.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

2
 
Option: label: test value: user_2

J'ai essayé de changer la boucle de cette facon mais ca n'a pas enlevé le problème:

                    label,
                    changedUser.getName());
            //option.setImage("public/images/edit.gif");
            System.out.println("Option: label: " + option.getLabel() + " value: " + option.getValue());
            options[i++] = option;
        }

l'erreur vient de la pages JSP il n'y a pas le ".options"
