make com.sun.faces.verifyObjects, only better
---------------------------------------------

         Key: MYFACES-1147
         URL: http://issues.apache.org/jira/browse/MYFACES-1147
     Project: MyFaces
        Type: New Feature
  Components: Implementation  
    Reporter: Dennis Byrne
 Assigned to: Dennis Byrne 
    Priority: Minor


The RI has a context parameter feature, com.sun.faces.verifyObjects .  This 
performs a whole bunch of QA for components, converters, renderers, and 
validators .  

MyFaces should do this also but add the following:

Do a file system check for all <to-view-id> in faces-config.xml
Look for duplicate map & list entries in faces-config.xml (currently allowed by 
both RI and MyFaces)
Look for duplicate managed beans in faces-config.xml (currently allowed by both 
RI and MyFaces)
Make sure each managed bean is in the classpath.
Make sure each <from-action> exists, and that it has the correct signature.

Mistakes should not throw exceptions, just logging to INFO .

Probably should just call it something like org.apache.myfaces.verify .

In the future, the real benifit would be to apply the same scrutiny to the 
JSPs.  I would like to do this by converting each one into a xml Document 
object first.  The only tool I found for this was jsp2XML.java, which is part 
of the old watchdog repo:

 PROTECTED]

I would appreciate it if anyone knew of an alternative.  Also, if anyone can 
think of anything else reasonable to test for at startup, put it here.
