Using Cake w/ url extensions

I am using CakePHP 2.0 (I believe it is v2.0.3.) and PHP 5.3.8.

I am working on an application which utilizes Cake's support for url
extensions. Specifically, I am outputing XML whenever a url request
ends in the .xml extension. If the url request is made without

any extension, then my application presents the stardard view. This
all works beautifully --

request .../controller/action.xml renders via view/controller/xml/
action.ctp while request .../controller/action renders via view/
controller/action.ctp.

To achieve this, I did the following:

1. Added support for url extension; added the following line to
route.php -- Router::parseExtensions('xml');
2. Added support request handling; added the following line to
MyController.php -- public $components = array('Session',
'RequestHandler');

To output xml, I am using Cake's 'XML' class in conjunction with PHP's
'SimpleXMLElement' class. My problem is that the complete xml is
never generated. The classes are suppose to generate xml based

on an input PHP array, however, it appears that the complete array is
not processed. My xml output is partial.

My source code in my view file (.ctp) is as follows:

$simple_xml_elem = Xml::build($xml_array);
echo $simple_xml_elem->asXML();

Interestingly, in the course of trying to debug this problem, I
discovered the a similar behaviour can be observed if I simple attempt
to dump the view object within the xml view file

(../view/controller/xml/action.ctp). 'var_dump($this)' only output a
partial dump of the view. The same view dump performed within the
standard view file (../view/controller/action.ctp) outputs a full

dump of the view.

It is my believe that Cake is somehow setting up the view environment
differently when it routes for a url extension than when the standard
view is requested.

Could some please shed some light on the for me before I lose my
hair. Please???? Thanks!
