-------------------------------------------------------------------

                 Key: JBSEAM-2419
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2419
             Project: JBoss Seam
          Issue Type: Bug
          Components: Core
            Reporter: Christian Bauer
            Priority: Minor


I can see this on the log on seamframework.org but can't reproduce it:

This is thrown from the FeedServlet.

The code doesn't do what the exception says it is doing:

    /**
     * Assigns the context variable 'currentAccessLevel' when no user is logged in.
     * @return Integer Guest access level.
     */
    @Factory(value = "currentAccessLevel", scope = ScopeType.SESSION, autoCreate = true)
    public Integer getGuestAccessLevel() {
        return ((Role)Component.getInstance("guestRole")).getAccessLevel();
    }

This has to be investigated further.
