Re: How do I get Cake 3.1 to reply to an AJAX request without requiring a layout .ctp file?

I discovered a bug in the Route.php file.
the reg expression used for finding extensions only works if no parameters are passed in the URL.
I have temporarily modified my Routes.php file to find the extension anywhere in the string and used str_replace to remove the .json from the url and I no longer get the action missing error.
I still get the template missing error though.

I have gone through the documentation, which is a bit too vague, and tried many things, but I still am getting an error that the template file is missing.

I had this working sending back a json response in 3.0 using ext='json', yet after updating to 3.1 it is broken. 

I checked the migration guide and tried changing ext  to _ext, setting up the Routes with:
Router::extensions(['json']);

in the controller method I am using the _serialize key which is supposed to render without the template:
$this->set('_serialize', ['salesPeople']);

The JsonView class does not appear to be loading and I don't see in the documentation where I am supposed to set it.
The documentation says ' you can automatically leverage the new view classes' By enabling RequestHandlerComponent in your application, and enabling support for the json and or xml extensions, but I have enabled it in the Initialize method of the controller and enabled the 'json' extension as mentioned earlier and it is still not working.

Here is the method in question:
public function getSalesPeopleSelectList() {
        $this->request->accepts('json'); // No direct access via browser URL
        $dealerId = $this->request->params['pass'][0];
        $this->RequestHandler->renderAs($this, 'ajax');
        //$this->viewClass = 'Json';
        $this->loadModel('SalesPeople');
        $salesPeople = $this->Purchases->SalesPeople->find('list')->where(['is_active'=>'1','user_id'=>$dealerId]);  //for salespeople options for autocomplete
        $this->set(compact('salesPeople'));
        $this->set('_serialize', ['salesPeople']);
    }


When I enable the _ext = json I get the following error:

2015-10-14 06:57:36 Error: [Cake\Controller\Exception\MissingActionException] Action PurchasesController::getSalesPeopleSelectList.json() could not be found, or is not accessible.

What have I missed?
