    Conversation as a Subsession

    sasha55

      Hello,
      I have the following problem, 2 use cases, that should work in parallel
      PageA working in separate conversation A
      PageB and PageBView, working in separate conversation B
      To implement such a behavior I use natural conversations with static ids, so that I always know that is the id of my conversation and can switch to it.


      Pages.xml




      <?xml version="1.0" encoding="UTF-8"?>
      <pages 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-2.2.xsd">
           <conversation name="conversationA" parameter-name="convId"
                parameter-value="conversationA" />
           <conversation name="conversationB" parameter-name="convId"
                parameter-value="conversationB" />
           <page view-id="/pageA.xhtml" conversation="conversationA">
                <description>pageA</description>
                <begin-conversation join="true" />
                <navigation from-action="#{manager.beginA}">
                     <redirect view-id="/pageA.xhtml">
                     </redirect>
                </navigation>
                <navigation from-action="#{manager.beginB}">
                     <redirect view-id="/pageB.xhtml">
                          <param name="conversationPropagation" value="none" />
                     </redirect>
                </navigation>
           </page>
           <page view-id="/pageB.xhtml" conversation="conversationB">
                <description>pageB</description>
                <begin-conversation join="true" />
                <navigation from-action="#{manager.beginA}">
                     <redirect view-id="/pageA.xhtml">
                          <param name="conversationPropagation" value="none" />
                     </redirect>
                </navigation>
                <navigation from-action="#{manager.beginB}">
                     <redirect view-id="/pageB.xhtml">
                          <param name="conversationPropagation" value="none" />
                     </redirect>
                </navigation>
                <navigation from-action="#{manager.pageBViewNameA}">
                     <redirect view-id="/pageBView.xhtml">
                     </redirect>
                </navigation>
                <navigation from-action="#{manager.pageBViewNameB}">
                     <redirect view-id="/pageBView.xhtml">
                     </redirect>
                </navigation>
           </page>
           <page view-id="/pageBView.xhtml" conversation-required="true"
                no-conversation-view-id="/pageB.xhtml" conversation="conversationB">
                <description>pageBView</description>
                <begin-conversation join="true" />
                <navigation from-action="#{manager.beginA}">
                     <redirect view-id="/pageA.xhtml">
                          <param name="conversationPropagation" value="none" />
                     </redirect>
                </navigation>
                <navigation from-action="#{manager.beginB}">
                     <redirect view-id="/pageB.xhtml">
                     </redirect>
                </navigation>
           </page>
      
      </pages>






      And menu to switch between pages and conversations looks like this,




      <h:panelGrid title="Menu">
           <h:outputLink value="pageA.jsf">
                <f:param name="convId" value="conversationA" />
                <h:outputText value="PageA" />
           </h:outputLink>
           <h:outputLink value="pageB.jsf">
                <f:param name="convId" value="conversationB" />
                <h:outputText value="PageB" />
           </h:outputLink>
      <h:commandBut





      The only problem in this approach is that I have to use h:outputLink
      to simulate conversation switch.


      Is there a better solution for this problem?
