Si sta definitivamente mescolando gli ambiti necessari. Quella vista dovrebbe trovarsi in un bean '@ ViewScoped'. Se hai bisogno dei valori in un'altra vista, passa semplicemente come parametri o mantieni ** solo ciò che ti serve ** su '@ SessionScoped'. In relazione al problema, se mi fornisci un [SSCCE] (http://sscce.org/) con il codice che posso copiare e incollare, sarò grato di fare alcuni test. Quali versioni di implementazione di jsf primefaces stai usando? –

+0

Primefaces 4.0 e JSF 2.2, Come posso fornire il codice? – Ajeesh

@XtremeBiker Ricevo l'errore quando fornisco ** ** tag ajax ma questo è necessario per caricare il successivo panelgrid. – Ajeesh

ho risolto l'errore. Non so perché Jsf abbia bisogno di inizializzare tutti i treenode all'interno del costruttore di bean. Inizializzato tutti i treenodes con valore di stringa vuoto e quindi tutto funziona correttamente. Funziona sia in Session/View Scoped bean.

UPDATE: 1 Questo errore può verificarsi anche a causa di updations ajax errati. Stavo cercando di fare una richiesta jax da ciascun componente e di aggiornare l'intero pannello (Componenti all'interno di un pannello). Quindi ho modificato gli aggiornamenti per aggiornare solo la vista specifica Eg. SelectOneMenu. La soluzione qui è aggiornare solo componenti specifici senza aggiornare l'intero modulo o vista.

UPDDATE: 2 ho cambiato nel file web.xml param-valore da false a true, allora il problema è risolto,

<context-param> 
    <param-name>javax.faces.PARTIAL_STATE_SAVING</param-name> 
    <param-value>true</param-value> 
</context-param>

Felice di vederlo. Probabilmente è legato al ciclo di vita dei componenti. Tuttavia non può vederlo senza il bean gestito correlato. –

@Xtreme Biker Ok, grazie per l'aiuto amico. – Ajeesh

Ho avuto un problema simile durante il passaggio a JSF 2.2, che anch'io ho risolto rimuovendo del tutto il context-param PARTIAL_STATE_SAVING. In precedenza avevo impostato su false per abilitare la soluzione alternativa discussa qui: http://balusc.blogspot.com/2010/06/benefits-and-pitfalls-of-viewscoped.html –

ho riparato impostando salvando il metodo dello stato di "server" invece di "client":

<context-param> 
    <description>State saving method: 'client' or 'server' (=default). See JSF Specification 2.5.2</description> 
    <param-name>javax.faces.STATE_SAVING_METHOD</param-name> 
    <param-value>server</param-value> 
</context-param>
