Black screen after changing a map

[MultiGTAMISSION 0]

Hello!
I am writing because I don't know what to do. I edit Metin2 4fun and I installed Inventory Slot Marking System and 6-7th bonus. It's okay when I log in but when I want to change map, black screen occurs and syserr:

1215 13:06:23302 :: Traceback (most recent call last):

1215 13:06:23303 :: 

This is the extract from uiAttr67Add.py that contains SetCanMouseEventSlot:

if app.WJ_ENABLE_TRADABLE_ICON:
		
		@staticmethod
		def IsSupportItem(inven_slot):
			dstItemVNum = player.GetItemIndex(inven_slot)
			if dstItemVNum == 0:
				return False

			return dstItemVNum in Attr67AddWindow.SUPPORT_DICT
		
		def RefreshLockedSlot(self):
			if self.inven == None:
				return

			for i in range(player.INVENTORY_PAGE_SIZE):
				self.inven.wndItem.SetCanMouseEventSlot(i)
			
			for i in (self.SupportSlotIndex, self.RegistSlotIndex):
				if i != -1:
					itemInvenPage = i / player.INVENTORY_PAGE_SIZE
					localSlotPos = i - (itemInvenPage * player.INVENTORY_PAGE_SIZE)
					if self.inven.GetInventoryPageIndex() == itemInvenPage:
						self.inven.wndItem.SetCantMouseEventSlot(localSlotPos)
						
			self.inven.wndItem.RefreshSlot()
			self.inven.RefreshMarkSlots()
		
		def BindInterface(self, interface):
			from _weakref import proxy
			self.interface = proxy(interface)

		def SetInven(self, inven):
			from _weakref import proxy
			self.inven = proxy(inven)
		
		def OnTop(self):
			if self.tooltipitem:
					self.tooltipitem.SetTop()

			if app.WJ_ENABLE_TRADABLE_ICON and self.interface:
				self.interface.SetOnTopWindow(player.ON_TOP_WND_ATTR_67)
				self.interface.RefreshMarkInventoryBag()

The line that syserr underline is:

				self.inven.wndItem.SetCanMouseEventSlot(i)

I also want to send extract from uiRefine.py where setCanMouseEventSlot and RefreshLockedSlot are defined.

		def SetCanMouseEventSlot(self, slotIndex):
			itemInvenPage = slotIndex / player.INVENTORY_PAGE_SIZE
			localSlotPos = slotIndex - (itemInvenPage * player.INVENTORY_PAGE_SIZE)
			self.lockedItem = (-1, -1)

			if itemInvenPage == self.wndInventory.GetInventoryPageIndex():
				self.wndInventory.wndItem.SetCanMouseEventSlot(localSlotPos)

		def SetCantMouseEventSlot(self, slotIndex):
			itemInvenPage = slotIndex / player.INVENTORY_PAGE_SIZE
			localSlotPos = slotIndex - (itemInvenPage * player.INVENTORY_PAGE_SIZE)
			self.lockedItem = (itemInvenPage, localSlotPos)

			if itemInvenPage == self.wndInventory.GetInventoryPageIndex():
				self.wndInventory.wndItem.SetCantMouseEventSlot(localSlotPos)

		def SetInven(self, wndInventory):
			from _weakref import proxy
			self.wndInventory = proxy(wndInventory)

		def RefreshLockedSlot(self):
			if self.wndInventory:
				itemInvenPage, itemSlotPos = self.lockedItem
				if self.wndInventory.GetInventoryPageIndex() == itemInvenPage:
					self.wndInventory.wndItem.SetCantMouseEventSlot(itemSlotPos)

				self.wndInventory.wndItem.RefreshSlot()

I don't have any idea to solve this problems. Every smaller ones I fixed but this seems to be complicated. Could you help me please?

Try to add this before the line

If(self.inven.wndItem!=0):

Hi, @ V0lvox

Thank you for your reply.

Well, the problem is now resolved but this time syserr told me about the same situation here:

self.inven.wndItem.RefreshSlot()

I've just copied that "if" and now it works!

Lastly, could you explain me why did this problem occur?

They are declared as 0. And on that point not initialised.
