StrutsNavigationHandler act as active navigation handler even for a pure jsf requests targetted
at myfaces Navigation Handler
-----------------------------------------------------------------------------------------------------------------------------

                 Key: WW-2572
                 URL: https://issues.apache.org/struts/browse/WW-2572
             Project: Struts 2
          Issue Type: Bug
          Components: Integration, Other
    Affects Versions: 2.0.11.1
         Environment: windows 2000 desktop, jdk1.5.0_10 and wintel86
            Reporter: sarav
            Priority: Critical


What is being attempted in the same web application (.war file)

1. set of jsf (jsp)pages processed through the struts2 and jsf (myfaces) lifecycle as in the
showcase example
2. another set of  jsf (jsp) pages processed only through the pure jsf lifecycle (myfaces
impl)

configured the request pattern in the web.xml to handle pure jsf requests (with pattern like
*.jsfaces)

when requesting a page like example.jsfaces the myfaces handles upto the point of render phase
then the flow is handed over to the StrutsNavigationHandler there by resulting in a null pointer
exception for some reason, although the faces-config.xml has the appropriate navigation rule
for requests coming in from example.jsfaces

from the log file:
2008-04-02 20:45:56,520 DEBUG (org.apache.myfaces.application.ApplicationImpl:179) - set NavigationHandler
= org.apache.myfaces.application.NavigationHandlerImpl

2008-04-02 20:46:00,739 DEBUG (org.apache.myfaces.application.ApplicationImpl:179) - set NavigationHandler
= org.apache.struts2.jsf.StrutsNavigationHandler

here is the stack trace:

looks like the above use case can not handled when there is a requirement for pure jsf lifecycle
and struts2-jsf integrated processing. is there a workaround /configuration where both the
type of requests could be processed



struts2-jsf-plugin-2.0.11.1.jar and myfaces-impl-1.1.2.jar are in the classpath
