I put together a basic test project.
Used the layout and the view tpl you provided.
I've got this as my controller function.
public function indexAction()
{
$jsonData = '--string from text file--';
$result = json_decode($jsonData);
var_dump($result);
}
I get a "hello world" and a var dump of the json data.
What needs to happen to the $results data for it to be used on the
layout/view?

My Layout:
<?php
// <meta>
$this->headMeta()
->appendHttpEquiv('Content-Type', 'text/html;
charset=UTF-8')
->appendHttpEquiv('Content-Language', 'en-US');
$this->headTitle()
->headTitle('My Page', 'APPEND');
echo $this->doctype('XHTML1_STRICT');
?>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<?= $this->headMeta() ?>
<?= $this->headTitle() ?>
</head>
<body>
<?= $this->layout()->content ?>
</body>
</html>
My View:
<h1>HELLO WORLD</h1>
In the course of debugging this, I've tried to take out all of the possible
bugs, I've narrowed it down to one thing: attempting to json_decode a
perfectly valid JSON string, which I've attached, prior to preDispatch(),
View, Layout rendering causes blank screen.
