> 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
