[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-1358) conversation stack not popping properly when used with pages.xml

Tue May 29 19:11:12 EDT 2007

     [ http://jira.jboss.com/jira/browse/JBSEAM-1358?page=all ]

Gavin King closed JBSEAM-1358.
------------------------------

    Resolution: Rejected

Correct, page actions ALWAYS execute on every request to the page. (An s:link with no explicit view attribute is a request back to the page.)

So to change this behavior, specify an explicit view on s:link.

> Assume there are two pages p1 and p2.  Entering p1 will start a conversation c1.  p1 contains a s:link to p2, which when clicked will start a new nested conversation c2.  In p2, there's a s:link that goes back to p1 by invoking action #{conversation.redirectToParent}.  
> The strange part.
> If the propagation=nested rule is specified as part of the s:link, then the redirectToParent is working okay and the conversationStack is consistent.
> If the propagation=nested rule is specified as part of p2.page.xml as <begin-conversation nested="true"/>, then the redirectToParent does not redirect to parent, and the conversationStack reports an additional duplicate entry for p2.
