>             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.
