java.lang.NullPointerException at org.primefaces.context.PrimeFacesContext.release

Question

Я всегда получаю сообщение об ошибке после развертывания моего приложения на рабочем сервере. В моей тестовой среде все работает нормально.

Вот StackTrace из GlassFish журнала:

Я использую JSF 2.2 с Primefaces 4.0. Спасибо за советы!

Answer 1

Глядя на этих двух кадров:

at org.primefaces.context.PrimeFacesContext.release(PrimeFacesContext.java:26) 
at org.primefaces.context.PrimeFacesContext.release(PrimeFacesContext.java:28) 

и исходный код:

24 @Override 
25 public void release() { 
26  RequestContext.getCurrentInstance().release(); 
27 
28  wrapped.release(); 
29 } 

(Reference: http://grepcode.com/file/repo1.maven.org/maven2/org.primefaces/primefaces/4.0/org/primefaces/context/PrimeFacesContext.java)

Он смотрит на меня как-то создал PrimeFacesContext что оборачивает null, а затем обернули это другим PrimeFacesContext. Очевидно, что это не так, чтобы обернуть null, так как NPE неизбежен, если вызывается release.

Проверьте код приложения, чтобы узнать, отвечает ли он за это.
