Delivery address refresh page - checkbox

-- HikaShop version -- : HikaShop Business: 2.6.3
-- Joomla version -- : 3.6.2
-- PHP version -- : 5.6.24-0

1. User add a item to cart.
2. Go to checkout.
3. Tick the checkbox of "Use the same address as payment".
4. Change the "Delivery address" in the popup. Click "OK".
5. The browser refresh the page and the "Use the same address as payment" is not ticked of anymore, but the address is added.

We have template overrides, but I have tried to remove these and the problem does still exists.

Hi,

I'm not able to reproduce the problem on your website.
When I arrive on the address view, the checkbox "Use the same address as payment" is already ticked. And if I untick it, I can fill in the delivery address and it will be used.
The problem I see however is that when the page refreshes, the checkbox is still ticked while it shouldn't. It seems to be related to the view overrides. Can you try with the default template of Joomla ? Are you able to reproduce the issue ?

It is the same error with the standard theme Atomic, that the page refreshes and untick the checkbox.

Have you seen the error before?

Hi,

No. It's the first time, as far as I remember.
The tick/untick selection of the checkbox is handled by the code: in the view file "address" of the "checkout" view. So I would start by checking the value of both $this->shipping_address and $this->billing_address with such code in the view:
echo $this->shipping_address . ' ' . $this->billing_address;
