as it turns out. with the bug fixed the mounts array is left null because the file does not exist yet. so further in the program is i try to add to the array, nothing happens.

and if i try "mounts = [[NSMutableArray alloc] init];" only the two arrays get the same pointer.

transportTypes = [NSArray arrayWithObjects:@"afp",@"smb",@"cifs",@"nfs",nil]; mounts = [[NSMutableArray alloc] initWithContentsOfFile:[[self applicationSupportFolder] stringByAppendingPathComponent:@"Bonjour Mounter.plist"]]; bonjourServices = [[NSMutableArray alloc]init]; AFPScanner = [[BonjourScanner alloc]init]; SMBScanner = [[BonjourScanner alloc]init]; NFSScanner = [[BonjourScanner alloc]init]; AFPScanner.bonjourServices = bonjourServices; SMBScanner.bonjourServices = bonjourServices; NFSScanner.bonjourServices = bonjourServices; [AFPScanner searchForService:@"_afpovertcp._tcp."; domain:nil]; [SMBScanner searchForService:@"_smb._tcp."; domain:nil]; [NFSScanner searchForService:@"_nfs._tcp."; domain:nil]; } return self; }

Have you fixed the [mounts initWithContentsOfFile:...] bug and it still happens?

I'm actually checking here in this function.
- (IBAction)mountSomeServers:(id)sender
{
   NSDictionary *mountDictionary;
   mountDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
                      [server stringValue], ServerNameKey,
                      [share stringValue], VolumeNameKey,
                      [type title], TransportNameKey,
                      @"", MountDirectoryKey,
                      [user stringValue], UserNameKey,
                      [password stringValue], PasswordKey,
                      [NSNumber numberWithBool:YES], AsyncKey, NULL];
   [mounts addObject:mountDictionary];
this is the only place where objects are being added to the mount array.

I checked the init function and as soon as the bonjourServices array is initialized witch is after the mounts array it is assigned the same pointer as the mounts array, and from what i can deduce it's because the mounts array is empty at the time, because the file it is trying to load does not exist yet.

I'm just guessing here, I've never encountered that kind of problem in 17 years of programing in any language. mind you i'm quite new to cocoa, but i did not face that problem in any of my other cocoa programs.

Which, if I recall correctly, is before bonjourServices is allocated. What do you think the problem is?
