Well, the only thing I get from the debugger is:

Loading program into debugger…

Program received signal: “EXC_BAD_ACCESS”.
I tried all sorts of different settings, because in the past I have
gotten a stack.

Without any hint about the stack, we cannot really help you, but
just give you some guess.

See code below. Get a error of “EXC_BAD_ACCESS” when I make
entries in the GUI. Code used to work with no problems. It
appears that it is doing an illegal substraction, which I think
means the objects are not being initialized with a value of 0. At
least that is my guess.
#import "MonthlyReport.h"
@implementation MonthlyReport
+ (void)initialize

if (self == [MonthlyReport class])

NSArray *keys = [NSArray arrayWithObjects:
@"reportCumActualCost", @"reportActualCost",

[self setKeys:keys
triggerChangeNotificationsForDependentKey

[self setKeys:keys
triggerChangeNotificationsForDependentKey

[self setKeys:keys
triggerChangeNotificationsForDependentKey

[self setKeys:keys
