Call to a member function get() on a non-object Symfony2

Hi I want to render a form in symFony2 with dynamic fields added to it. So I have wrote code in controller as:

public function getDataAction(){
    $handler = new AnotherClass();
    $object = $handler->getForm($getAdditionalData);
}

and "AnotherClass" defined as following:

class AnotherClass extends  Controller implements requiredInterface{

public  function getForm($formData){
 //Here i want to write Logic to render a dynamic form with dynamic fields
    $form = $this->createFormBuilder($formData)
             ->setAction($this->generateUrl('me_route_go'))

        // Set form field of additional data
         foreach ($formData as $k => $v) {
             $form->add($k, 'text');
         }

         //Create form and submit button
         $form = $form->add('submit', 'submit')->add('Cancel', 'reset')->getForm();
         $form = $form->getForm();
     }
  }

 }

But here I am getting following error:

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

return $this->container->get('form.factory')->createBuilder($type, $data, $options);

Please suggest what could be the issue.

thanks in advance..

Your controller AnotherClass requires the Dependency Injection Container since you are extending the base Controller class, you have to set it after you instantiate it :

public function getDataAction(){
    $handler = new AnotherClass();
    $handler->setContainer($this->container);
    $object = $handler->getForm($getAdditionalData);
}

You can also create it as a service :

services.yml

name.of.your.service:
    class:     Path\To\AnotherClass
    calls:
        - [setContainer, [ "@service_container" ]]

And then :

public function getDataAction(){
    $handler = $this->get('name.of.your.service');
    $object = $handler->getForm($getAdditionalData);
}
