[JBoss Seam] - problem with Starting conversations with GET requests
by jason_rency
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.

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"
