I guess so. My intention is to have the NSArrayController following 
the changes in the mutable array in order to show these changes in a 
tableview in the GUI. As I understand it, to accomplish this the 
NSArrayController should observe the changes in the array. Doing 
simply [array addObject:] apparently does not trigger the 
NSArrayController into having the tableview follow the change.
