Prestashop 1.6 payment module order state

Question

I created payment module for Prestashop 1.6.1.1.

The problem is with updating order state after customer returns from banks website. I can not get cart from context as shown on examples.

For example, this is controller, which is executed, when customer presses cancel button on bank:

class MyModulePaymentCancelModuleFrontController extends ModuleFrontController{
    public function initContent(){
        $cart = $this->context->cart;
    }
}

The cart value is null. It seems like the cart has been deleted / discarded prior to the controller.

In the contrary, I get proper cart from context in MyModule Payment ModuleFrontController (creating order) and MyModulePayment Return ModuleFrontController (payment completed successfully).

Could anyone please point me in the right direction.

Answer 1

Looks like cart is destroyed as soon as order is created. I sent order id to the bank, which I expected to be returned and then used that as reference point for updating orders.
