Bonjour tout le monde!

Lorsque je charge ma page web j'ai une erreur sur la page de type Java.LangException. En fait c'est parce qque l'erreur retournée est un null pointeur Exception.
J'ai ma petite idée sur "qui" lève cette erreur, je pense que c'est une histoire de context, et qu'elle est levée ici :

Citation de la javadoc ELContext

public abstract class ELContext
extends Object

Context information for expression evaluation.

To evaluate an Expression, an ELContext must be provided. The ELContext holds:

a reference to the base ELResolver that will be consulted to resolve model objects and their properties
a reference to FunctionMapper that will be used to resolve EL Functions.
a reference to VariableMapper that will be used to resolve EL Variables.
a collection of all the relevant context objects for use by ELResolvers
state information during the evaluation of an expression, such as whether a property has been resolved yet

Class ElBeanResolver

public Object getValue(ELContext context, Object base, Object property)
throws NullPointerException, PropertyNotFoundException, ELException {

if (context == null) {
throw new NullPointerException();
}

Et voici la trace de l'erreur :

Tous mes Bean sont en scope SESSION.
Dans la vue, j'itère sur des formulaires et pour chaque formulaire je veux accéder à son bean pour afficher des infos.
Toutes mes Listes sont de type String donc à priori je n'ai pas besoin de converter.

Impossible donc pour moi de trouver la cause de cette erreur.

Je ne sais pas s'il y aura beaucoup de monde la veille de Noël sur ce forum, mais si vous passez, alors Joyeux Noel!

La classe ListDistribManagementBean qui contient un PeopleEntity mapper dans une base de donnée et qui possède une liste de FormEntity( Ce sont eux qui possèdent des listes de group, div et bu mais comme elles sont sérializées, j'ai dû créer un FormEntityBean qui possède de vraies listes et une référence au formulaire correspondant.

[tchize_]

soit ejbDAO est null, soit ejbDAO.getOrganization() retourne null dans com.ste.crw.bean.global.FormEntityBean.getSourceListGroup(FormEntityBean.java:53) (cf votre stacktrace).

A vous de voir lequel pour savoir comment corriger (ajoutez des tests)

[joploya]

Merci pour votre réponse.

J'avais rajouté un affichage "IS NULL" à l'intérieur du bloc if(sourceListGroup == null) et le programme passe bien deux fois dans dans la méthode getSourceListGroup() : la première fois il passe dans le if et affiche le null, puis il passe dans getTargetListGroup() et il repasse dans getSourceListGroup() sans passer dans le if, preuve que la list a bien été instanciée et donc que ejbDAO n'a pas e de problème à priori lorsqu'il a été appelé.

Mais en effectuant des déplacement des instanciations, j'ai mis l'instanciation de sourceListDivison dans le constructeur. Celle-ci appelle une méthode de pickListGestion (qui est injectée comme ejbDAO et qui est en scope session), eh bien le programme plante directement dans le constructeur avec la même erreur. Donc ça doit effectivement venir des injections.

Mais dans PickListGestion j'appelle également des méthodes de ejbDAO, le scope est le même, les injections sont les même, etil n'y a aucun soucis.

En fait la classe pickListGestion est a peu près la même que FormEntityBean sauf qu'elle gère uniquement 3 pickLists qui ne sont associée à aucun formulaires.

Est ce que le fait que je gère des bean dans un repeat au niveau de la vue peu poser problème? Faut-il utiliser un autre scope que session?
