Hey all, I'm experiencing some weirdness with NSManagedObject. Basic background, I have an NSManagedObject 'surveyGroup', which has a to-many relationship to another NSManagedObject, surveyResults.
I'm attempting to access the surveyResults object in two different methods. It works fine in the first method, but in the second method I get the error: "-[NSManagedObject objectID]: unrecognized selector sent to class" When trying to access any of the properties of the surveyResult object. If I comment out the first method, the second method is able to access the properties of the surveyResult object without error. Am I doing anything obviously wrong here that would leave surveyResult un-usable the next time I try to access it? NSUInteger index = 0; NSMutableSet *surveyResultSet = [group mutableSetValueForKey:@"survey_results"]; NSMutableArray * surveyResultArray = [[NSMutableArray alloc] init]; [surveyResultArray addObjectsFromArray:[surveyResultSet allObjects]]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"date" ascending:YES]; [surveyResultArray sortUsingDescriptors:[NSArray arrayWithObject:sortDescriptor]]; [sortDescriptor release]; NSManagedObject * surveyResult = [surveyResultArray objectAtIndex:index]; NSManagedObject * survey = [surveyResult valueForKey:@"survey"]; NSString * surveyName = [survey valueForKey:@"name"]; NSString * title = [NSString stringWithFormat:@"%@", surveyName]; [surveyResultArray release]; return title; _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
