[jboss-user] [JBoss Seam] - conversation propagation and navigation
 rule

2007-05-05


With seam 1.2.1.GA, I tried this code:


|   <page view-id="*">
|      <navigation>
|         <rule if-outcome="fundList">
|           <redirect view-id="/FundList.xhtml">
|              <param name="conversationPropagation" value="none" />
|           </redirect>
|         </rule>
|      </navigation>
|   </page>
|

and I got this exception:

So how to specify no conversation propagation from navigation rule inside pages.xml?
