             Summary: JPDL Pageflow broken in JSF2
                 Key: JBSEAM-4944
                 URL: https://issues.jboss.org/browse/JBSEAM-4944
             Project: Seam 2
          Issue Type: Bug
          Components: JSF Integration
    Affects Versions: 2.3.0.BETA1
         Environment: JBOSS 7.1 + JSF2 + RichFaces 4.2.0.Final
            Reporter: Andrea Martino


The pageflow navigation is broken in Seam 2.3.0.Beta1 when using JSF2.0.

I defined a pageflow as following:

{code:xml|title=pageflow.jpdl.xml}
<?xml version="1.0" encoding="UTF-8"?>

<pageflow-definition name="captureorder">

    <start-state>
        <transition name="customersearch" to="customersearch"/>
    </start-state>
    
    <page name="customersearch" view-id="/customersearch.xhtml">
    	<transition name="customeroverview" to="customeroverview" />
    </page>
	
    <page name="customeroverview" view-id="/customeroverview.xhtml" />

</pageflow-definition>
{code}

The page customersearch.xhtml calls a method in the controller that returns "customeroverview" as following:

{code:xml:title=customersearch.xhtml}
<h:form>
    <h:inputText id="name" value="#{customerSearch.name}" />
    <h:commandButton value="Search" action="#{customerSearch.search}" />
</h:form>
{code}

The browser is never redirected to the "customeroverview" page.

Somehow the class *org.jboss.seam.jsf.SeamNavigationHandler* in method *handleNavigation* calls baseNavigationHandler (the last method) instead of  Pageflow.instance().navigate (which would be correct in this case)

{code:title=org.jboss.seam.jsf.SeamNavigationHandler}
   @Override
   public void handleNavigation(FacesContext context, String fromAction, String outcome) 
   {
      if ( !context.getResponseComplete() ) //workaround for a bug in MyFaces
      {
         if ( isOutcomeViewId(outcome) )
         {
            FacesManager.instance().interpolateAndRedirect(outcome);
         }
         else if ( Init.instance().isJbpmInstalled() && Pageflow.instance().isInProcess() && Pageflow.instance().hasTransition(outcome) )
         {
            Pageflow.instance().navigate(context, outcome);
         }
         else if ( !Pages.instance().navigate(context, fromAction, outcome) )
         {
            baseNavigationHandler.handleNavigation(context, fromAction, outcome);
         }
      }
   }
{code}

The reason for this behavior, is that *Pageflow.instance().isInProcess()* returns false, even if the page with the form was reached inside a pageflow.
