Seam pageflow example NumberGuess Not landing on to the second page

Question

I'm trying to run simple Seam PageFlow example NumberGuss. I have deployed it on Jboss Server. When I access the URL it lands on the first page but if I hit any of the button provided on that page it says "The page isn't redirecting properly".On server log I found

SEVERE [javax.enterprise.resource.webcontainer.jsf.application] (default task-16) Error Rendering View[/debug.xhtml]: org.jboss.weld.context.NonexistentConversationException: WELD-000321: No conversation found to restore for id 1.

I'm using wildfly-8.1.0 and jboss-seam-2.3.1

Attaching pageflow.jpdl.xml and numberGuess.xhtml for reference. Please help me resolve the issue I'm facing.

Resolved the issue.Weld is scanning the archive, which seems to cause the problem.The Weld Docs says: You can either set this up for your deployment only by adding the following content to the META-INF/jboss-all.xml file of your application. jboss-all.xml file goes to your META-INF for ear archive and likely to WEB-INF for war archive

<jboss xmlns="urn:jboss:1.0">
<weld xmlns="urn:jboss:weld:1.0" require-bean-descriptor="true"/>
</jboss>

It worked for me.
