David Beaumont commented on WELD-549:
-------------------------------------
Isn't the point of the h:link tag to enhance bookmarkability, so you can share
links make your site easier for spiders etc. If the default is to propagate the
conversation you have at best created yourself a memory leak and bugs from
conflicting state. At worst you will start writing your application around this
propagation and will have lost all the benefits of the new tag anyway and make
a poor web site for your users.
Whilst understanding you are the JSF experts not me, I really think the default
should be not to propagate.

> 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

> 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>
