Nicklas Karlsson commented on WELD-549:

Dan appears to have been thinking about this at some point. From the header block of ConversationAwareViewHandler:

 * QUESTION should we do the same for getResourceURL?
 * TODO we should enable a way to disable conversation propagation by URL
 * @author Dan Allen

>                 Key: WELD-549
>                 URL: https://jira.jboss.org/browse/WELD-549
>             Project: Weld
>          Issue Type: Bug
>          Components: Web Tier integration (JSF, JSP, EL and Servlet) 
>    Affects Versions: 1.0.1.Final
>         Environment: GlassFish Server Open Source Edition 3.0.1 on Mac OS 10.6 and Windows 7. WELD-000900 1.0.1 (SP2)
>            Reporter: David Beaumont
>            Assignee: Nicklas Karlsson
>             Fix For: 1.0.2.CR1
>         Attachments: CdiConvoBug.war
> I created a long running conversation by running a method on a conversation scoped bean:
> private boolean initialized;
> public void init() {
> 	if(initialized) return;
> 	conversation.begin();
> 	initialized = true;
> }
> From a facelets page using the JSF2 event system:
> <f:metadata>
> 	<f:event type="preRenderView" listener="#{convoBean.init}" />
> </f:metadata>
> If a conversation has been made long-running, the h:link tag will produce links with the conversation query parameter, thereby propagating the conversation whether that was what you wanted or not.
> I.e:
> <p>Link: <h:link outcome="page2.xhtml" value="a link" /></p>
> produces
> <p>Link: <a href="/CdiConvoBug/page2.jsf?cid=3">a link</a></p>
