get feature values

[Chirs]

Hi there,

I try to get products and features useing following functions:

	public function initContent(){
    	parent::initContent();		
		$id_lang=(int)$this->context->language->id;
		$this->context->smarty->assign(array(
	    'all_products' =>$this->getAllProducts(),
    	'all_features'=>$this->getAllFeatures()  
		));
    
		$this->setTemplate('display.tpl');
  	}   

	public function getAllProducts(){
  
    $id_lang=$this->context->language->id;
	
	$productObj = new Product();
    $products = $productObj -> getProducts($id_lang, 0, 0, 'id_product', 'DESC' );
	
	return $products;  
  }
  
  public function getAllFeatures(){
  
    $id_lang=$this->context->language->id;
    $all_features = FeatureCore::getFeatures($this->context->language->id);

	return $all_features;    
  }

My issue is that $all_features just contains feature.names, but not values. I don't find a way to get the values as well. Any hints for me?

Thanks, Chris
