I rethought your problem and guess that you don't extend the controller 
shipped in mvc_extjs. Just extend 
Tx_MvcExtjs_MVC_Controller_ExtDirectActionController instead of 
Tx_Extbase_MVC_Controller_ActionController.

If you have another inheritance structure and need to use another 
controller implement initializeView like this to get rid of the error:

/**
  * Initializes the View to be a Tx_MvcExtjs_ExtDirect_View that renders 
json without Template Files.
  *
  * @return void
  */
public function initializeView() {
	if ($this->request->getFormat() === 'extdirect') {
		$this->view = 
this->objectManager->create('Tx_MvcExtjs_MVC_View_ExtDirectView');
	$this->view->setControllerContext($this->controllerContext);
		}
	}

The reason is, that the FLOW3 package ships an own PHP based view to 
render json directly. You have to assign it in your controller as it is 
expected in the RequestHandler.
