PHP Cake - Controller - Code completion

Hello,

1st: Great product, I really like that IDE. (old IntelliJ user).

I have a small problem and I would like to know if I can not find the solution or if the feature does not exist.

I am using CakePHP, and when in a controller classe like:

class JsonController extends AppController {
var $helpers = array ('Html','Form','Translation');   
var $name = 'Json';
var $uses = array();

     function research_notes_save()
      {
          $this->Session->read

the code completion does not work on Session and read.

Is there a way to "activate" that?

Thanks in advance
