re: Multiple validation errors. Why?
I have a core data application. One entity is Hit. This entity typically has no instances when the application starts, and gets populated during the execution of the program. All of the instances appear to be OK when viewed in a TableView. Some or all instances may get deleted before the application quits. If any instances remain when the app quits, I get a multiple validation errors occured message. The console has no error messages. In debugging, I have gone so far as supplying no data at all when adding any instances, so they get created with default values only. Still I get the error message. Some attributes are strings, some are 16 bit integers, and some are 32 bit integers. The string defaults are empty strings, and the integer defaults are zero. I am creating Hit instances with this method The NSError has an -userInfo dictionary with at least some answers to your questions in it. - Ben ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Stick this in your app delegate:
- (NSError*)application:(NSApplication*)application
willPresentError:(NSError*)error
{
if (error)
{
NSDictionary* userInfo = [error userInfo];
NSLog (@encountered the following error: %@, userInfo);
Debugger();
}
return error;
}

Thanks. That was just the help I needed. Console messages showed that I needed
to explicitly set the value of one of the string attributes, which was defined
with a minimum length of zero and a blank default value. Once I
programmatically set the value to @ the errors went away. Things are looking
up.

I am creating Hit instances with this method NSManagedObject *newHit = [NSEntityDescription insertNewObjectForEntityForName:@Hit inManagedObjectContext:[appDelegate managedObjectContext]]; The app has three other entities, but they don't cause validation errors.
