jsf - Logout message doesn't show -

When I log out of my application it does not show my logout message

I have an output text to show the message in my output ( & lt; h: outputText id = "message" value = "# {loginMB.message}" /> ):

  & lt ;? Xml version = "1.0" encoding = "UTF-8"? & Gt; & Lt ;! DOCTYPE Structure PUBLIC "- // W3C // DTD XHTML 1.0 Transcription // N" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> & Lt; Ui: Composition xmlns = "http://www.w3.org/1999/xhtml" xmlns: f = "http://java.sun.com/jsf/core" xmlns: H = "http: // Java. Sun.com/jsf/html "xmlns: o =" http: // java.sun .com / JSF / Facet "Template =" / Web-ANF / Template / Template.XMAMT "& gt; & Lt; Ui: Define name = "content" & gt; & Lt; o: include in form id = "login" view = "true" & gt; & Lt; H: output text id = "message" value = "# {loginMB.message}" /> ... other components ... & lt; / o: form & gt; & Lt; / Ui: defined & gt; & Lt; / ui: Composition & gt;   
  And this is my backing bean:   
  @ManagedBean @ session executes the public-skilled user BB Serializable {Private string message; Public Zero Logout () {try {message = "You have successfully loggedout"; SecurityUtils.getSubject () logout () .; Faces.invalidateSession (); Faces.redirect ("login.xhtml"); } Hold (exception exception) {... another code ...}} public string getMessage () {return message; } Public Zero Set Message (String Message) {this.message = message; }}   
 Why does not this show my logout message?  
  Edit:   
  Logout method:   
  Public Zero Logout () { SecurityUtils.getSubject (). Logout (); Messages.addFlashGlobalInfo ("You have logged out successfully"); Faces.invalidateSession (); Faces.redirect ("? Login.xhtml to face-redirects = true & amp; lo = t"); }   
  Logout button:   
  & lt; p: commandButton action = "# {userBB.logout}" value = "logout" />    
 
 
 
  Why does not this show my logout message?    
 Because you have handed it as the property of a session and then canceled the session and sending a redirect. The invalidation of the session will destroy the area of ​​the session and all the items stored therein will be destroyed, including session dressed beans. After that the redirect will create a new request and session, and all the sessions in the session will be re-managed to the managed beans, all the properties will be set to the default.  
 There are 2 problems with this approach:  
 
 To display the message (s),  & lt; h: Output Text & gt; Instead of   & lt; h: Message (message) & gt;  
 Store the message in the session area instead.   
 To resolve your problem,  & lt; h: Message (message) & gt; Use the message (s) and  FacesContext # addMessage ()  or, as you already have to add a message in OmniFaces, its utility class, face reference You are using  & lt; h: message globalOnly = "true" & gt;  to display only the global message (like  null  containing the customer ID] Thus, everyone should:  
  & lt; h: message id = "message" globalonline = "right" />   
 / Code>   @ManagedBean @RejectScoped // Special work does not need to leave the session. Public class UserManager {Public Zero Logout (exception) {SecurityUtils} GetSubject (). Logout (); Messages.addFlashGlobalInfo ("You have logged out successfully"); Faces.invalidateSession (); Faces.redirect ("login.xhtml");}}   
 For interest, here's how it will use "plain JSF":  
  Public Zero Logout () throws exceptions {SecurityUtils.getSubject () .log out () ; FacesContext reference = FacesContext.getCurrentInstance (); context.addMessage (empty, new FacesMessage ("You have successfully logged out")); ExternalContext External Contact = Reference .getExternalContext (); externalContext.getFlash () setKeepMessages (right). ExternalContext.invalidateSession (); externalContext.redirect ("login.xhtml"); }   
 Important note is that you need a minimum 2.1.27 to get rid of all those problems.
