How does overriding OrderController.php affect cookies?

[Amazzing]

Hello,

 

I just came up with a strange overrides performance, or bug. Dont' know, what is this yet.

 

Here is what I have:

 

First of all, I have an override for Cart.php

override/classes/Cart.php

in this overrinde, I am updating getOrderTotal (...) function. 

I have added some cookie values to determine whether checkbox was checked or not.

$context = Context::getContext();

if (Tools::getValue('ens') == 1) { 
$context->cookie->ens = Tools::getValue('ensval'); 
}
elseif (Tools::getValue('ens') == 2 ){
$context->cookie->ens = 0; 
}

It works just fine. Cookie value is saved and visible on any page.

 

But this cookie value is not saved at all if I create an override for OrderController. 

This happens, even if there is nothing overriden in OrderController:

(I am overriding it to /override/controllers/front/OrderController.php)

<?php
class OrderController extends OrderControllerCore
{
}
?> 

As soon as I delete OrderController override or rename it, cookies are working fine again.

 

So, how does overriding OrderController affect cookies?
