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
