I have what looks like an odd race condition surrounding my bindings.
I have an NSCollectionView that is a list of images. I believe all of
the bindings to be hooked up correctly (and code-reviewed by 2 other
engineers familiar with NSCollectionViews.)
Some code snippets:
---
@implementation AppController
-(void)awakeFromNib {
NSLog(@"AppController::awakeFromNib");
[...]
pictureListController = [[PictureListController alloc] init];
[pictureListController showWindow:nil];
---
@implementation PictureListController
@synthesize imagesArray; // @property(nonatomic, retain)
- (id)init {
// self = [super init];
// [self setImagesArray:[NSArray array]];
[self adjustPictureArray];
NSLog(@"[DEBUG] about to initWithWindowNibName:@PictureList");
[self initWithWindowNibName:@"PictureList"];
NSLog(@"[DEBUG] AFTER initWithWindowNibName:@PictureList");
return self;
}
[...]
#define KEY_KEY @"KEY"
#define IMAGE_KEY @"IMAGE"
- (void)adjustPictureArray {
NSLog(@"[DEBUG] adjustPictureArray -awakeFromNib");
NSMutableArray *mArray = [NSMutableArray arrayWithCapacity:10];
NSDictionary *pictDict = [DataModel picturesDict];
for (NSString *key in [pictDict allKeys])
{
NSImage *image = [DataModel pictureDictWithID:[key intValue]];
NSMutableDictionary *imageDict = [NSMutableDictionary
dictionaryWithObjectsAndKeys:
key, KEY_KEY,
image, IMAGE_KEY,
nil];
[mArray addObject:imageDict];
}
[self setImagesArray:[NSArray arrayWithArray:mArray]];
}
---
When I run this code, I get:
2009-06-11 07:41:11.092 app[76813:10b] [DEBUG] adjustPictureArray -

I can change things around to do them in a different order and get the
error to come out for key 'KEY' instead of 'IMAGE', but it's basically
the same problem. If I break on the code and examine my array (the
referencedObject), it's an array of dictionaries, with keys KEY and
IMAGE, as expected, long before the view displays.
Am I missing some best-practices thing, here? Is there a special
ordering in which I need to do this stuff? I swear this worked a week
ago and I didn't change anything (other than to install the new SDK
<sigh>)
Thanks!
