[ https://issues.jboss.org/browse/WFLY-6706?page=com.atlassian.jira.plugin.... ] Robert Smith commented on WFLY-6706: ------------------------------------ Hi Brian, A few notes. 1. We are using Primefaces JSF. The error occurs in a @RequestScoped bean - following is the actual code: public void logout() { ... HttpSession session = (HttpSession)FacesContext.getCurrentInstance().getExternalContext().getSession(false); log.debug("Invalidated session " + session.getId()); if(session != null){ ExternalContext ec = FacesContext.getCurrentInstance().getExternalContext(); ec.invalidateSession(); try { ec.redirect(ec.getRequestContextPath() + "/xhtml/logout.xhtml"); } catch (IOException e) { log.error("Exception occurred logging out.", e); } } } the logout.xhtml is just a display screen that indicates the user is logged out. It include a css file and reads a language file. 2. I have run the application on Wildfly 9.0.2.Final using the standalone profile without seeing this error. 3. We are currently testing using a domain configuration with a *single *node and it happens every logout. 4. We are not sharing sessions. We are running the dc, host controller, process controller and server on a single linux vm. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
