Hi,
During init time (awakeFromNib), I build a list of objects into a mutable
dictionary, keyed by an [NSManagedObject objectID].
I load the objects up, then check to see if there are any NSManagedObjects
in the managedObjectContext with the same name as the objects I load during
init time. If they aren't there, I create a new NSManagedObject. Then I put
my object in the dictionary, keyed by the NSManagedObject I either found or
created.
This procedure works fine for new documents.
But when I am loading from a file, I can't find any init-time method that
can access the fully loaded managedObjectContext.
I have overrided many methods trying to find where the NSPersistentDocument
is fully loaded, the one that is documented for NSDocument is called
"initWithContentsOfURL"
- (id)initWithContentsOfURL:(NSURL *)absoluteURL ofType:(NSString *)typeName
error:(NSError **)outError
{
self = [super initWithContentsOfURL:absoluteURL ofType:typeName
error:outError];
NSLog(@"the context is size %d during initWithContentsOfURL", [[[self
managedObjectContext] registeredObjects] count]);
return self;
}
this returns a context of size 0, other methods I have tried include
awakefromnib, configurePersistentStoreCoordinatorForURL,
windowControllerDidLoadNib, etc. All return 0 for [[[self
managedObjectContext] registeredObjects] count].
I have referred the mailing list archive message:
http://lists.apple.com/archives/cocoa-dev/2005/Oct/msg00993.html
but this doesn't solve the problem.
Also - I am using 10.4 (I think the only difference here is the new
configurePersistentStoreCoordinatorForURL method)
Thanks in advance
