I've copied my cart summary into a new page.
I see my cart like if it was in checkout_cart_index, that's ok.
But when I change a quantity and click on "update shopping cart", the page reloads and that's it.
Reason : this page has no code in controller to handle this.
Question : how can use the controller of the cart inside my new page ?
Probably not possible, I'll probably have to copy the controller in my page controller. But is there a more simple solution ?
