Probleme de navigation avec JSF

**Evenmor** · 13/01/2009, 22h47

Bonjour,
Alors voila j'utilise jsf 1.1 avec tomcat 6.
A travers netbeans, j'utilise l'interface graphique pour effectuer les navigations entre page (je sais que ce n'est pas forcement bien, mais je ne m'y connais pas vraiment).
J'ai donc dans une page un tableau qui recupere des informations en BD et un bouton pour aller sur la page suivante.
Seulement je ne comprend pas pourquoi lorsque je lance l'application, tout fonctionne. Puis lorsque je clique sur le bouton, une erreur apparait :

Jan 13, 2009 4:34:13 PM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet Faces Servlet threw exception
java.lang.NullPointerException

avec une erreur 500.

Je crois comprendre qu'un element est à null...mais je n'en ai pas et je ne parviens pas a utiliser le pas a pas pour suivre le fonctionnement.
Je ne sais plus trop quoi faire.
Merci pour votre aide.

Bonjour,

Pourrais tu nous montrer le code de ta page JSF, de l'action liée au bouton, ainsi que ton faces-config.xml (et tant qu'à faire, le web.xml

) ?

Je signale aussi que j'utilise une classe serializable crée par mes soins dans mon code à l'initialisation de ma page.

Merci pour votre aide.

Merci

**Sniper37** · 15/01/2009, 17h33

le problème peut être dans un des composants, peut être pas un problème de navigation.
le code de la page me parait un peu compliqué, c'est généré par netbeans?
c'est quoi comme composants les ui..?

**Evenmor** · 15/01/2009, 17h43

Casiment tout est généré par netbeans oui.
Les ui que j'utilise sont des imagehyperlink et une table.
La table est rempli par l'intermédiaire de ma classe personnalié avec des informations tirées d'une BD.
J'ai remarqué que si je n'initialise pas l'instance de ma classe (donc la table reste vide) alors la navigation fonctionne. Mais cela ne m'arrange pas vraiment car si ma table reste vide...elle ne sert donc à rien.

De plus le mode debug ne fonctionne pas. Je m'explique, sur l'action de mon imagehyperlink la fonction suivante est appelé

Code :

    public String imgl_right_action() {
        HttpServletRequest request = (HttpServletRequest)getFacesContext().getExternalContext().getRequest();
        HttpSession session = request.getSession(true);      
 
        session.setAttribute("icurrentXRcomp", "1");
 
        return "NextReccord";
    }

Mais si je met un point d'arret au debut de la fonction. L'errur 500 apparait sans meme passer par mon point d'arret. L'erreur apparait tout de suite.

**Evenmor** · 16/01/2009, 17h14

J'ai remarqué que ce n'était pas uniquement la navigaiton mais n'importe quels boutons. Si je rajoute des boutons sur ma page sans meme ajouter d'event à ce dernier.
Lorsque je clic dessus, rien ne devrait se passer et pourtant mon message d'erreur apparait malgré tout.
qu'est ce qe ca peut bien etre?
