When a warning is display after an on-site checkout, checkbox in cleared but the not the due date. To reproduce : - on patron's account, check 'on-site checkout' box ; see the date due is set for today at 23:59 - try to checkout an item not allowed for on-site checkout (because of the itype, notforloan != 0, etc.) - a warning box 'Please confirm checkout' is displayed - refuse the checkout --> the checkbox 'on-site' is now empty, but the dus date remains field for today. I don't know which behavior is the best : let the box checked, or emptied the date ?
