IllegalStateException in seamspace example

                 Key: JBSEAM-1341
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1341
             Project: JBoss Seam
          Issue Type: Bug
          Components: Examples
    Affects Versions: 1.2.1.GA
            Reporter: Valerij Timofeev
            Priority: Trivial

"Already a member?" link in register.xhtml page propagates conversation (s:link), so after clicking this link and after that again "SIGN UP!" button a factory method RegisterAction.start() is trying to start another long running conversation although the 1st one is still running.

This results in an exception: java.lang.IllegalStateException: begin method invoked from a long running conversation, try using @Begin(join=true) on method: start

Possible solutions:
<s:button value="Cancel" action="#{register.cancel}" styleClass="registerButton"/> 
1) <s:link view="/home.seam" value="Click here to log in 2" propagation="none" />
2) But in order to explicitly end current converstaion it would be better to implement RegisterAction.cancel() method with the @End annotation and use the following link:
<s:link view="/home.seam" action="#{register.cancel}" value="Click here to log in"/>
