[jboss-user] [JBoss Seam] - Re: How to use conversationPropagation=

[tazo]

Came here as soon as i checked cvs log :)

Looks like conversationPropagation="none" works fine now. Just one note! My original code (look at my first post) didn't work: 'entity' is conversational component and it was unavailable in postback because of disabled propagation. <s:link> works fine in this situation.

And, Gavin, your recent changes in Manager.java broke workspace management:


  | 	<h:dataTable value="#{conversationList}" var="entry">
  | 	    <h:column>
  | 	        <h:commandLink action="#{entry.select}" value="#{entry.description}"/>
  | 	         
  | 	        <h:outputText value="[current]" rendered="#{entry.current}"/>
  | 	    </h:column>
  | 	</h:dataTable>
