I apologize beforehand if this is not the right place to ask.

I have a problem when handling TTntListView's OnEdited event when
multiselect and ownerdraw are true. The event receives a wrong TTntListItem.

Steps to reproduce:

1. Drop a TTntListView component on a form
2. Set MultiSelect to true
3. Set RowSelect to true
4. Set OwnerData to true
5. Add some items to the list view (through OnData event)
6. Enter the editing mode on Item1
7. Enter some text, do not press Enter or lose focus
8. While Item1 is in edit mode select Item2. Item2 will be renamed
instead of Item1. OnEdited event handler will receive Item2 as "Item"
argument, not Item1.

With native VCL TListView component everything is fine.

Now another trick (more strange)
1. Declare TTntListItem as your TForm's private member as FSavedItem
2. Handle the OnEditing event and save the reference to "Item" argument
(the one being edited) in FSavedItem.
3. Enter the editing mode on Item1 (reference to Item1 will be saved in
FSavedItem)
4. Enter some text, do not press Enter or lose focus
5. Set breakpoint in OnEdited handler to check FSavedItem
6. While Item1 is in edit mode select Item2. The debugger will stop at
the breakpoint. Check the FSavedItem - it refers to Item2, not Item1!

The one below is a rare bug but might give some clue:
1. Add some items to the list view (through OnData event)
2. Enter the editing mode on Item1
3. Enter some text, do not press Enter or lose focus
4. While Item1 is in edit mode move mouse cursor over Item2
5. While mouse cursor is over Item2 press Enter to finish editing Item1.
Item2 will be renamed instead of Item1. OnEdited event handler will
receive Item2 as "Item" argument, not Item1.
