IllegalStateException: getAttribute: Sessione già invalidato

Domanda

Ho un problema con il mio primo JSF / IceFaces (versione 1.8.2) applicazione in esecuzione su JBoss 5.1.0.

ricevo un'eccezione dopo un po ', mi diceva di problemi di sessione. Questo è strano, perché io non uso le sessioni nel mio codice a tutti. I seguenti registri mostrano che nessuno dei miei fagioli backing può essere un'istanza a causa di questo errore (da JBoss):

I riconosciuto che l'eccezione viene generata una mezz'ora dopo l'ultima attività dell'utente.

Soluzione

Lo stesso problema è stato riscontrato sui ICEfaces forum:

Le soluzioni proposte sono stati:

Questo stava accadendo per noi una volta abbiamo impostato la modalità asincrona off

<context-param>
    <param-name>com.icesoft.faces.synchronousUpdate</param-name>
    <param-value>true</param-value>
</context-param>  
Quando questo era falso abbiamo ottenuto la bella sessione di poco scaduta messaggio. Quando questo era vero, il comportamento di timeout della sessione era traccia dello stack.

Nel frattempo ho passato da ICEfaces 1.8.2 a ciò che è nel repository svn al momento (1.8.3+). E il comportamento è cambiato. Non v'è più alcun incidente.

Per quanto riguarda la sua dichiarazione che non si utilizza la sessione ovunque, lo stacktrace dice che sta tentando di creare una sessione con scope bean gestito quando questa eccezione è stato gettato. Così si sono sicuramente utilizzando la sessione:)

Aggiorna come per i commenti: Si dovrebbe anzi sicuramente non assegnare la (richiesta in base !!) FacesContext come variabile static. Inoltre, l'iniezione di altri fagioli deve essere presa dal luogo in <managed-property> faces-config.xml. In caso contrario, non è "iniettando" a tutti, ma solo manualmente accesso l'altro di fagioli. Con l'iniezione, si sta lasciando JSF fare il lavoro per impostare l'altro di fagioli come una proprietà del chicco di corrente. Un esempio può essere trovato qui .

Altri suggerimenti

Il motivo per l'eccezione era nelle mie classi SessionBean.
Ho chiesto in precedenza se il motivo può essere l'iniezione di fagioli in un altro attraverso il FacesContext. Ora dò la risposta la mia auto: "Sì, può essere la ragione"

public class MySessionBean {
    private static FacesContext facesContext = FacesContext.getCurrentInstance();
    private utils.AnotherSessionBean injectedSessionBean = (utils.AnotherSessionBean) facesContext.getApplication().getELResolver().getValue(facesContext.getELContext(), null, "anotherSessionBean");
    // ...
}

mi sono sentito libero di istanziare l'esterno FacesContext attuale di qualsiasi metodo o il costruttore, che non era una buona idea, perché dopo la sessione-timeout ho usato quello vecchio o Mabey nessun contesto di sessione. MySessionBean è stata ricaricata o ottenere una nuova istanza di esso, ma non aggiornare la FacesContext. Il risultato di questo è descritto sopra ^^

In conclusione. Quindi, ricevendo il FacesContext appartiene alla codeblock di un metodo o costruttore

La ringrazio molto per il vostro aiuto!
