PhpStorm 4 code auto completion

I have a controller in CakePHP 2.2 application.
I use PhpStorm 4.0.1 as IDE.

In MyController.php file I declare this:

    /**
     * @property MyUtilComponent $MyUtil
     */

1. Inside my controller, when I write `$this->` I can select "MyUtilComponent" from drop down list.
2. But when I write `$this->MyUtilComponent->` no function name option comes to select.


3. When I write $this->MyUtil->addThis(); and then click to addThis word and "Go to declaration", then PhpStorm goes to method's declaration successfully.

What should I do more to get function names autocompletion ?

Note: The behaviour is same for the core components.
