Add <propagation type="?"/> as a child to <rule> or <redirect/> / <render/> in pages.xml
----------------------------------------------------------------------------------------

                 Key: JBSEAM-1296
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1296
             Project: JBoss Seam
          Issue Type: Feature Request
          Components: Core
    Affects Versions: 1.2.1.GA, 1.2.0.GA
            Reporter: Chris Rudd


While you can add a the propagation via a parameter its a bit verbose and cluttered (due to the value binding string literal) 

<page view-id="/editDocument.xhtml">
    
    <navigation from-action="#{documentEditor.update}">
        <rule if="#{documentEditor.errors.empty}">
            <end-conversation/>
            <redirect view-id="/viewDocument.xhtml">
                <param name="conversationPropagation" value="#{'none'}"/>
            </redirect>
        </rule>
    </navigation>
    
</page>

Adding a <propagation type="?"/> would be much cleaer.

<page view-id="/editDocument.xhtml">
    
    <navigation>
        <rule if-outcome="done">
            <end-conversation/>
            <redirect view-id="/viewDocument.xhtml">
                <propagation type="none"/>
            </redirect>
        </rule>
    </navigation>
    
</page>


Side note : 
The reason for needing to control the propagation in the circumstance above is so that the target view (/viewDocument.xhtml) can start with a new clean conversation. The redirect mechanism delays the end of the conversation untill it gets to the redirected to view, but I dont want that conv to be used. The before-redirect attribute doesnt work in this case as the redirect url needs to include data from the existing conversation (page parameters). I use the same scenario in other places via s:link/s:button but I cannot do this here as its dependent on the outcome not what link/button I pressed
