def Refresh(self):
        for i in xrange(shop.OFFLINE_SHOP_SLOT_COUNT):
            itemCount = shop.GetOfflineShopItemCount(i)
            if (itemCount <= 1):
                itemCount = 0
            self.itemSlotWindow.SetItemSlot(i, shop.GetOfflineShopItemID(i), itemCount)
            
        wndMgr.RefreshSlot(self.itemSlotWindow.GetWindowHandle())
        
    def LoadDialog(self):

I think the problem is from function GetOfflineShopItemID because it returns none but i don t have any idea what to do.
