Symfony2 twig rendering error

Hey all I am trying to render a twig template in my controller but instead i get this error:

Error: Call to a member function has() on a non-object

I followed few exampled on line and according to these I should be fine, unfortunately I guess I am doing something wrong.

My controller code:

<?php

namespace Tomazi\SiteBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Tomazi\SiteBundle\Factories\FactoryHomePage;

class IndexController extends Controller
{
    public $home;

    public function __construct(
        FactoryHomePage $home
    ){
        $this->home = $home;
    }

    public function indexPageAction()
    {
        return $this->render('pages/home.html.twig', [
            'name' => 'Tomazi'
        ]);
    }
}

So my twig file src is app/Resources/view/home.html.twig

in this file I have:

<h1>Hey {{ name }} </h1>

Why do i get this error message?

Update 1 OK so my controller was declared as a service, this did not allowed me to use twig container i belief....

I then went back and configured my controller to be just a Controller like so:

<?php
namespace Tomazi\SiteBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class IndexController extends Controller
{
    public function indexPageAction()
    {
        return $this->render('pages/home.html.twig', array('name' => 'Tomazi'));
    }
}

I also had to of course change my routing so it does not expect a service but just a controller.

After these changes I was able render my home.html.twig, But this not satisfied me as I really wanted my Controller to be a service because I wanted to inject my Factories into it that will prepare all the data for the Controller to Respond and I like THIN controller approach...

To actually achieve my goal I had to add a service_container argument to my Controller service like so:

<!-- Controller -->
<service id="tomazi.sitebundle.controller.index"
         class="Tomazi\SiteBundle\Controller\IndexController">
    <argument type="service" id="tomazi.sitebundle.factory.index" />
    **<argument type="service" id="service_container" />**
</service>

Now my final version of a controller looks like this:

<?php

namespace Tomazi\SiteBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\DependencyInjection\ContainerInterface;
use Tomazi\SiteBundle\Factories\FactoryHomePage;

class IndexController extends Controller
{
    public $home;

    public $container;

    public function __construct(
        FactoryHomePage $factoryHomePage,
        ContainerInterface $containerInterface
    ){
        $this->home = $factoryHomePage;
        $this->container = $containerInterface;
    }

    public function indexPageAction()
    {
        return $this->render('pages/home.html.twig', array('name' => 'Tomazi'));
    }
}

Not to sure if this is the best approach but it does the trick for me.

OMG the reason why It was not working because my Controller was a service..... :@, I changed it so that my Controller is standard bang it works..... But I want my Controller to be a Service..... so how can I find a way around it...? is is possible to create Twig container as a service and inject it into my Controller Service?

Could you try this code ?

public function indexPageAction()
{
    return $this->render('pages/home.html.twig', array(
        'name' => 'Tomazi'
    ));
}
