[jboss-user] [JBoss Seam] - session scoped variable lost after page action

[FredF]

Hello

I have a facelet view that triggers an page action when it loads.

<page view-id="/userPage.xhtml">
  | 		<param name="member" value="#{visitedUserAction.member}" />
  | 		<action
  | 			execute="#{visitedUserAction.initContentProviderAccount}" />
  | 	</page>

@Stateful
  | @Name("visitedUserAction")
  | @AutoCreate
  | public class VisitedUserActionBean implements VisitedUserAction {
  | 
  | 	private String segment;
  | 
  | 	private String member;
  | 
  | 	@EJB
  | 	private ContentProviderAccountDao contentProviderAccountDao;
  | 
  | 	@Out(required = false, scope = ScopeType.SESSION)
  | 	private ContentProviderAccount contentProviderAccount;
  | 
  | 	@Logger
  | 	private Log log;
  | 
  | 	public void initContentProviderAccount() {
  | 		log.info("getting current visited contentProviderAccount for page=" + member);
  | 
  | 		ContentProviderAccount contentProviderAccount = null;
  | 		try {
  | 			contentProviderAccount = contentProviderAccountDao.findByStageUrlName(member);
  | 			log.info("fetched contentProviderAccount=" + contentProviderAccount);
  | 			if (contentProviderAccount.getProviderSegment().name().toLowerCase()
  | 					.equals(segment.toLowerCase())) {
  | 				log.info("setting contentProviderAccount to " + contentProviderAccount);
  | 				this.contentProviderAccount = contentProviderAccount;
  | 			} else {
  | 				// fixme: redirect to either user not found page or search page
  | 				throw new RuntimeException("user does not exist in segment, however there is one in: "
  | 						+ contentProviderAccount.getProviderSegment().toString());
  | 			}
  | 
  | 		} catch (ContentProviderAccountDaoException e) {
  | 			// fixme: redirect to either user not found page or search page
  | 			throw new RuntimeException("user is not found ");
  | 		}
  | 
  | 	}
  | 
  | 	@Create
  | 	public void logthis() {
  | 		log.info("will this run?");
  | 	}
  | 
  | 	public String getSegment() {
  | 		return segment;
  | 	}
  | 
  | 	public void setSegment(String segment) {
  | 		this.segment = segment;
  | 	}
  | 
  | 	public String getMember() {
  | 		return member;
  | 	}
  | 
  | 	public void setMember(String member) {
  | 		this.member = member;
  | 	}
  | 
  | 	@Destroy
  | 	@Remove
  | 	public void destroy() {
  | 	}
  | 
  | }


Then I want to find the sessionscoped variable and inject it into another stateful bean.


@javax.ejb.Stateful
  | @Name("artistpresentaton")
  | public class ArtistPresentationActionBean extends com.yourstardom.middle.ArtistPresentationActionBase
  | 		implements com.yourstardom.middle.ArtistPresentationActionLocal,
  | 		com.yourstardom.middle.ArtistPresentationActionRemote {
  | 
  | 	@In
  | 	private ContentProviderAccount contentProviderAccount;
  | 
  | 	...
  | }

This works fine when I do a non-faces request to the view but when I execute an action in the ArtistPresentationActionBean from the view and the response is rendered, contentProviderAccount is null and I get the exception

Caused by javax.el.ELException with message: "javax.ejb.EJBTransactionRolledbackException: In attribute requires non-null value: artistpresentation.contentProviderAccount"

why?
