Bonjour,

J'ai un problème pour afficher les tâches d'une façon dynamique dans un calendrier using primefaces.

Il y a toujours des erreurs et des exceptions

Maintenant je suis bloquée avec exception "java.lang.NullPointerException"

classe facade

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

public List<Agendatache> getTache(){
        Query query = em.createNamedQuery("Agendatache.findAll");
        return query.getResultList();
    }

classe controller

    }
    @PostConstruct
    public void initSchedule() {
        listtache = agendatacheFacade.getTache(); //getTache() méthode dans la classe façade qui affiche la liste des tâches.
        Agendatache tache = new Agendatache();
        String desc = "";
        Date datedebut = new Date();
        Date datefin = new Date();
        for (Agendatache agendatache : listtache) {
            desc = tache.getDescripTache();
            datedebut = tache.getDateDebut();
            datefin = tache.getDateFin();
            eventModel.addEvent(new DefaultScheduleEvent(desc, datedebut, datefin));

        <p:ajax event="eventResize" listener="#{scheduleController.onEventResize}" update="messages" />  
 
    </p:schedule>

SVP aidez moi, je serai très reconnaissance pour vous, avec tout mon respect.

Bonjour ayasaidi,

Pourrais tu montrer le log concernant l'erreur?

EDIT:

Je pense que tu devrais mettre

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

<p:schedule id="schedule"  editable="true" value="#{scheduleController.eventModel}" widgetVar="myschedule">

[ayasaidi]

Je l'ai changé Mais le même problème.

Oups! Je viens de le remarquer: private List<Agendatache> listtache n'est pas initialisée. Tu pourrais modifier le constructeur de la classe

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
public ScheduleController() {
         eventModel = new DefaultScheduleModel(); // par contre, eventModel est initialisé deux fois: ici et lors de sa déclaration...
         listtache = new ArrayList<Agendatache>();
    }

Même exception

Voilà ce qui arrive quand l'on se concentre sur Schedule...
Modifie: @ManagedBean(name = "scheduleController") et public class ScheduleController implements Serializable.
