Comment ce problème est-il provoqué et comment puis-je le résoudre? J'utilise Mojarra 2.1.2.

[RESOLU]

Il a fallu des jours pour diagnostiquer ce problème, mais finalement je suis en mesure de résoudre ce problème.

C'était en fait @ViewScoped et il possède un objet DAO de propriété gérée qui n'a pas été sérialisé. Donc, une fois la vue rendue, les facettes produisent également cette exception, mais la vue JSF est déjà rendue et c'est pourquoi cette exception est apparue.

Solution: Rendre tous les objets sérialisés en @ViewScoped bean, et marquez "transitoire" qui ne sont pas sérialisés comme dans mon cas c'était un objet DAO dans JSF @ViewScoped.

Faisal Basra

La raison en est que:

  1. JSF stocke la structure du composant de page dans HttpSession
  2. Si le contenu de la page est très volumineux et que la session n'a pas été créée précédemment, une réponse peut avoir été écrite et l'erreur ci-dessus se produit

La solution consiste donc à créer la session avant l'impression de la page Facelet (/ JSP). Un exemple grossier pourrait être comme:

@PostConstruct
void initialiseSession() {
    FacesContext.getCurrentInstance().getExternalContext().getSession(true);
}

Je l'ai mis dans mon web.xml pour résoudre le problème pour l'une de mes applications.

<context-param>
    <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
    <param-value>client</param-value>
</context-param>

Ce qui est étrange cependant, c'est que j'ai plusieurs autres applications hébergées sur cette même instance de fish de verre qui ne nécessite pas ce vaudou dans le web.xml.

Je veux fermement croire que ce n'est pas la solution, car cela n'a aucun sens pour moi pourquoi cette application en particulier l'exige et les autres non. Mais pour l'instant ça marche.

Ça m'arrivait aussi.

J'ai utilisé Mojarra 2.1.13 et après l'avoir mis à jour vers 2.1.29, le problème s'est résolu sans aucune modification de mon code.
