Terre:
Thanks for the effort, but I have also been able to set up a basic
Controller / Layout / View and get my code to work. There still
appears to be some kind of intractable issue going on here that has to
do with json_decode and Zend MVC will my existing code base. I'm going
to try to refactor my code, and get this working. I'll report back my
findings.
