CakePHP 3.0-dev3 Xml Request Handling

Hi

I'm wondering what the correct method of serializing models for XML output should be?

After getting XML request routing working, via explicitly specifying xml in the Router::parseExtensions() call, I'm getting an error when doing a serialize on a paginated model.

The error is 

<response>

<script/>

<message>

DOMText::__construct() expects parameter 1 to be string, object given

</message>

<url>/authors.xml</url>

<code>500</code>

</response>

In my AuthorsController, the action is:

public function index() {

$authors = $this->paginate($this->Authors);

$this->set(array(

'authors' => $authors,

'_serialize' => array('authors')

));

}

In AppController, I have 

public $components = array('RequestHandler');

In routes.php I have

Router::mapResources('authors');

Router::parseExtensions(['xml']);

I have Template/Authors/index.ctp, but I'm expecting that to get used for the HTML request only.  The .xml extension should use the XmlView.

The URL usage is http://localhost/authors.xml

The error trace is:

2014-05-20 23:28:55 Error: [DOMException] DOMText::__construct() expects parameter 1 to be string, object given

Request URL: /authors.xml

Stack Trace:

#10 {main}

I guess because of the way that Models have changed, perhaps a ResultSet can not simply be serialized to XML that way that we might have done previously.

Is what I'm doing expected to work?
