NSArrayController removes fails, sort of

Show all headers | View raw

I have an NSTableView column bound to an NSArrayController which itself 
is bound to an NSMutableArray. The data is displayed as expected, but 
when I remove an item, although it does disappear from the table, the 
change is not written to disk when the application quits. I use 
NSKeyedArchiver to persist the array to disk upon quitting. When the 
application quits, the original array including the removed items is 
written to disk. 

I did some debugging and found that after the items are removed from the 
array controller, the underlying array does indeed reflect the removal, 
but something happens between there and quitting the application that 
brings the removed items back into the array.

My application also uses an NSPopupButton to display these same items. 
It is also bound to the same array controller as the table view column. 
I suspect that this is somehow a problem, but can someone enlighten me?
TIA
