Symfony 2 - can't clear cache - You cannot create a service ("request") of an inactive scope ("request")

Question

whenever I try to clear the cache on the console I get the following error:

 [Symfony\Component\DependencyInjection\Exception\InactiveScopeException]   
  You cannot create a service ("request") of an inactive scope ("request").

Has anyone experienced this before? Thanks.

Edit: Sample of code:

//accessing request object
namespace Greg\TestBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\DependencyInjection\ContainerInterface;
use HvH\APIschemaBundle\Controller\Validation;
use HvH\APIschemaBundle\Controller\Helpers;

//FOSRestBundle
use FOS\RestBundle\View\View;

class TestController extends Controller
{
    public function testAction(Request $request) 
    {                       
        //get any query strings
        $query_strings = $request->query->all();
        return($query_strings);
    }
}

For example to manually create scope "request" in CLI you may overload the initializeContainer kernel method in AppKernel class, simply by doing:

class AppKernel extends Kernel {
    public function registerBundles() {
        // ...
    }

    public function registerContainerConfiguration(LoaderInterface $loader) {
        // ...
    }

    protected function initializeContainer() {
        parent::initializeContainer();
        if (PHP_SAPI == 'cli') {
            $this->getContainer()->enterScope('request');
            $this->getContainer()->set('request', new \Symfony\Component\HttpFoundation\Request(), 'request');
        }
    }
}

Fixed this problem by removing the request object in the constructor. As the CLI is headless there is no 'request' object unless it's manually created.
