I have an application that has an NSArrayController bound to an NSTableView (all of the columns, not the table itself) that was working fine. I was working on something else in the application and when I went back to test it I noticed I was getting an error when I removed an object from the array (also using bindings). The error is: -[NSCFArray objectAtIndex:]: index (-1( or possibly larger)) beyond bounds (4). Where 4 is the length of the array (making it 1 greater than the maximum index). Using the debugger I see that it is the updateSelectionIndexes that is causing this (preceded by NSTableBinder).

Has anyone run into this?
