[TYPO3-50-general] TYPO3 Neos with 404 error page

[Ngeth Chanthorn]

Dear All,

I am a new user of TYPO3 Neos, I am using 1.0 alpha 2. I would like to 
ask you some ideas related to 404 error page configuration.I have 
configured some configuration in Settings.yaml like:

TYPO3:
   Flow:
     error:
       exceptionHandler:
         renderingGroups:
           notFoundExceptions:
             options:
               templatePathAndFilename: 
'resource://MyPackage/Private/Templates/Error/Index.html'

By using above configuration, I can display my own content in 
Index.html, but what I really want is to display 404 error page as 
normal content in the same template as home content and others.
Do you have any ideas to do this?

I am looking forward to get your feedback,

Kind regards,
Chanthorn
