[weld-issues] [JBoss JIRA] Commented: (WELD-549) Conversation propagated by default with h:link

[Marcel Kolsteren (JIRA)]

    [ https://jira.jboss.org/browse/WELD-549?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12551245#action_12551245 ] 

Marcel Kolsteren commented on WELD-549:
---------------------------------------

Just a comment related to the possibility of dropping the ConversationAwareViewHandler. The getActionURL method now covers four cases:

1. form actions
2. link hrefs
3. Ajax calls, and
4. redirect URLs

According the the Weld documentation (5.3.2. Conversation propagation), the conversation is automatically propagated in all cases except 2. So I think dropping the ConversationAwareViewHandler is only possible if there is another solution for covering 1, 3 and 4.

> 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>
