      Hi all,

      I tried to invoke a method in a session bean when rendering a page.
      the problem is when the page is rendered by using a newly created browser, the method can't be invoked and the following exception is thrown.

      10:05:46,706 ERROR [PhaseListenerManager] Exception in PhaseListener RENDER_RESPONSE(6) beforePhase.

      the method can be invoked when the page is rendering by a page action within the same page with no exceptions.

      I defined a page action in the pages.xml like this: 

      <pages>
 <page view-id="/home.xhtml" action="#{login.test}"/>
</pages>


      the session bean where the method and the same page page acction is defined: 


      package src.reg.server;

import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Out;
import org.jboss.seam.contexts.Contexts;
import org.jboss.seam.core.FacesMessages;

@Stateless
@Name("login")
public class LoginAction implements Login
{

 @In @Out
 private Reguser reguser;

 @PersistenceContext
 private EntityManager em;

 private String rnd;


 public String test()
 {
 int i=0
 rnd = i;
 i++;

 System.out.println("the next rnd is:"+rnd);
 FacesMessages.instance().add(rnd);
 return rnd;
 }

public String login()
 {
 Reguser user;
 user = em.find(Reguser.class, reguser.getUid());
 System.out.println("the current rnd is:"+rnd);
 if ( user==null )
 {
 FacesMessages.instance().add("USER ID wrong");
 return "login";
 }
 else
 {
 return "main"
 }
 }

}



      the login page: login.xhtml
