[solved] Re: [SHALE] Still not getting to resulting page based on navigation rules

[Rick Reumann <st...@reumann.net>]

I knew I was trying to combine to many different things at once 
(MyFaces/Shale) but it took Craig to wake me up to realize it and 
recommended I go back to starting small. I backed out the Shale stuff 
and said let me go back to just MyFaces. By comparing my web.xml with 
the MyFaces example web.xml, I realized that I had somehow left out:

<!-- Listener, that does all the startup work (configuration, init). -->
     <listener> 
<listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
     </listener>

What's odd is thte application was sort of working without it. My 
navigation rules weren't working without it though. I put back the shale 
stuff and now I both are behaving nicely.

Oh well, thanks for all your patience. When I finally get a handle on 
this, I'll have a simple MyFaces/Shale app that will be VERY basic that 
others will hopefully get some use from when just starting out. I'll try 
to write it up in a step-by-step guide at some point.
