Hi Graham,
Thanks for your help. I put an NSLog for returnValue on the line before
return. I also put a conditional breakpoint on return to break if returnValue
== 0. The NSLog confirmed that returnValue was indeed set to 22. The
conditional breakpoint did not break yet my tableView still responds as if
returnValue = 0. Just to make certain that I didn't screw up my conditional
breakpoint I reset it to break if returnValue =22. It did break. Maddening!
As I debug I can clearly see that the program is not going through the other
path. It is definitely traveling through the path that I am logging.
Everything says that returnValue is 22 except the actual tableView. By the way
when the program does use the other path everything works fine. So there is
something about my code in here:
- (int) numberOfRowsInTableView: (NSTableView *)aTableView{ unsigned int
returnValue = 0; if (aTableView == gameScoresTableView) //This works
as expected { if (currentIndex_>= 0) {
LNPlayer *currentPlayer = [playersArray objectAtIndex: currentIndex_];
NSMutableArray *tempGameRecordsArray = [NSMutableArray
arrayWithArray: [currentPlayer gameRecordsArray]];
returnValue = [tempGameRecordsArray count]; NSLog
(@"returnValue = %d", returnValue); //NSLog prints>> returnValue = 22;
} else { NSBeep ();
NSLog (@"ERROR in LNAppController -- numberOfRowsInTableView:");
return 0; } } else
if (aTableView == playerManagementTableView) //This is the one that doesn't
work { returnValue = [playersArray count]; //[playersArray
count] = 22 NSLog (@"playersArray count = %d", returnValue);
//returnValue = 22 NSLog (@"returnValue = %d", returnValue);
//NSLog prints>> returnValue = 22; } NSLog
(@"returnValue = %d", returnValue); //NSLog prints>> returnValue = 22;
return returnValue; //Conditional breakpoint set to returnValue == 0 does
not break. But a conditional breakpoint set to returnValue == 22 does break!}
that is wrong but I can't figure out what it is.
Also if on the first line I don't initialize returnValue to 0 I get my zillion
rows. The NSLog just before return still says returnValue = 22.
