Symfony2 get request in action called in twig

I have a twig template with : 

{% render controller('MyBundle:Default:leftside') %}

So i have an action leftside in my controller : 

public function leftsideAction(Request $request)

I'm trying, in this action to retrieve GET parameters with : 

$request->get('MY_PARAM')

But it's always empty, i think, because i render this action in my template, i can't retrieve all my request.

How can i do that ?

That's totally expected due the concept of request stacks.

The Request supplied to "main" action is, well, MASTER_REQUEST, while those supplied via render controller tag are SUBREQUEST.

You can read more about RequestStack feature here.

Now, in order to have access parameters defined in MASTER_REQUEST you need to get request_stack service and then get the master request. After that, it's business as usual:

public function leftsideAction(Request $request){
    $stack = $this->get('request_stack');
    $master = $stack->getMasterRequest();

    $master->get('MY_PARAM'); // This should work
    $request->get('MY_PARAM'); // But this should not
}

Here is the definition of RequestStack class: link
