Description
Run attached files.

Apply custom string converter using according button.
Select Any item from the list.
Add any item to the list. 

You could see in code of string converter, that there is a counter of calls and name of item will contain the number of method call.

You could see items in the list with numbers 10, 11, 12, 13. That is much more calls, then needed for items drawing.

As I see now, mostly perfomance. DB-request, http-request for image etc..

Is this just a performance concern, or is there some functional bug that you've identified here?
