Prestashop 1.6 core controller override

[rosuandreimihai]

I am trying to override a core controller protected function within PrestaShop 1.6.1. The controller is AddressController.php

The override controller looks like:
 

    class AddressController extends AddressControllerCore
    {
    
          
        /**
         * Assign template vars related to countries display
         */
        protected function assignCountries()
        {
            $this->id_country = (int)Tools::getCountry($this->_address);
            // Generate countries list
            if (Configuration::get('PS_RESTRICT_DELIVERED_COUNTRIES')) {
                $countries = Carrier::getDeliveredCountries($this->context->language->id, true, true);
            } else {
                $countries = Country::getCountries($this->context->language->id, true);
            }
    
            // @todo use helper
            $list = '';
            $product_by_country = Configuration::get('TOOLPRODUCTCOUNTRY_PRICE');
            foreach ($countries as $country) {
                if($product_by_country==1){
                    if (isset(Context::getContext()->cookie->productcountry_delivery)) {
                        $selected = ((int)$country['id_country'] === Context::getContext()->cookie->productcountry_delivery) ? ' selected="selected"' : '';
                    } else {
                        $selected = ((int)$country['id_country'] === $this->id_country) ? ' selected="selected"' : '';
                    }
                } else {
                    $selected = ((int)$country['id_country'] === $this->id_country) ? ' selected="selected"' : '';
                }
                $list .= '<option value="'.(int)$country['id_country'].'"'.$selected.'>'.htmlentities($country['name'], ENT_COMPAT, 'UTF-8').'</option>';
            }
    
            // Assign vars
            $this->context->smarty->assign(array(
                'countries_list' => $list,
                'countries' => $countries,
                'sl_country' => (int)$this->id_country,
            ));
        }
    
    }

Basically, I want to show in the checkout steps as default country another one than selected in PrestaShop BO for the `$('#id_country')` drop down list. The country desired is chosen before the checkout process and is stored as `productcountry_delivery`.
The problem is that this code is not taken into consideration by Prestashop, as if it wouldn't exist.
I have removed the class_index.php from cache folder to force a recompile but yet again with no succes

Could someone help me figure this out?

Thank you!

Maybe the override is working correctly, but I remember that countries are stored in a JavaScript variable (not sure), maybe that's why you can't see any change.

No, I also tried to place a die() command at the begin of the function and nothing..

clear cache manualy cache/smarty/cache/ and cache/smarty/compile - clear even u don't use the cache  

[rosuandreimihai]

Nope, that didn't worked.. I cleared the cache as mentioned but still with no effect

The problem is that I use in the same time another override for another controller and that one works flowless..

 

There is something happening with this one and I cann't figure it out..
