    Seam Not capturing view

    Ali Gohar Newbie

      Hi,


      I am facing an issue with seam to capture the old view. Here is the scenario:


      I've configured this in components.xml


           <event type="org.jboss.seam.security.notLoggedIn">
             <action execute="#{redirect.captureCurrentView}"/>
           </event>
           <event type="org.jboss.seam.security.postAuthenticate">
             <action execute="#{redirect.returnToCapturedView}"/>
           </event>
      


      Now I've defined a page which requires login, here is that page's xml file (Note that I am using a separate pages.xml file for each page)



      <page xmlns="http://jboss.com/products/seam/pages"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.1.xsd"
           no-conversation-view-id="/pages/view-cart.xhtml"
           login-required="true">
           
           <param name="itemId" value="#{viewCartAction.itemId}" converterId="javax.faces.Long"/>
      </page>



      Now, I want if a person is not logged in and access view cart, he should be redirected to login page first and then straight to view cart after logging in. It works fine if i use s link like this:


      <s:link view="/pages/view-cart.xhtml">
         <f:param name="itemId" value="1222"/>
      </s:link>
      


      But now consider this scenario, At one page on click of a button, i outject a list of objects in conversation scope. Then I redirect the page to view-cart.xhtml page but in this case the user is not redirected to the login page, instead it is taken to view-cart directly :(


      Just to give an examlple in my another bean I've the code:


      //declared at top in class
      @out(required=false)
      private List<Item> items;
      
      //method
      public String buyItem(){
      items = someitemsList; //list of some items
      return "/pages/view-cart.xhtml";
      }


      Now when buyItems method is invoked, it tries to redirect to view-cart page, in this case user should have taken to the login page, but this is not the case, instead it is taken to view-cart page :(


      Does anybody know what am i doing wrong here?


      Any help will be appreciated.


      Thank you

          this is the pages.xml for the hotel booking example:


          have you tried using the same strategy as below (mainly the login-view-id in the pages tag and the login-required attribute for the page tag)?  you can also configure it such that all pages require login (using *).


          <?xml version="1.0" encoding="UTF-8"?>
          <pages xmlns="http://jboss.com/products/seam/pages"

                  <action if="#{validation.failed}"
                     execute="#{register.invalid}"/>
              
                  <navigation>
                      <rule if="#{register.registered}">
