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

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?
