title: Error Rendering View: java.lang.IllegalStateException: Cannot create a session after the response has been committed
body: <p>I'm developping an entreprise application on jboss AS 7.1.
  I was reading answers to those question (<a href="https://stackoverflow.com/questions/8072311/illegalstateexception-cannot-create-a-session-after-the-response-has-been-commi">Q1</a> and <a href="https://stackoverflow.com/questions/10844536/java-lang-illegalstateexception-cannot-create-a-session-after-the-response-has">Q2</a>) asking for the same problem then mine and the solution was to upgrade to the Mojarra 2.1.9.
  I'm using maven but i'm not referencing any Mojarra jar dependency as it's provided by jboss server and i don't know which version it uses itself and since those questions have been asked a long time ago then i don't know if the solution is just to add dependencies to my pom to override the version used by jboss(normally, jboss AS 7.1 has overcome this problem already, i don't understand why it still happen to me)..
  Which version should i add or what is the best solution at this moment ?</p>
  
  <p>Cheers.</p>
