I am encountering a problem opening a CoreData based document in my
application. The document saves without any errors, but when I try to
open it, this message is logged to the console:
[NSArrayController presentError:]: selector not recognized [self =
0x44119f0]
2005-08-26 13:10:04.362 Seagull 3[6515] *** NSRunLoop ignoring
exception '*** -[NSArrayController presentError:]: selector not
recognized [self = 0x44119f0]' that raised during posting of delayed
perform with target 4e0ac00 and selector 'invokeWithTarget:'
NSArrayController does not respond to presentError:, so I think this
is a bug in CoreData. In order to determine what the error was, I
subclassed NSArrayController and implemented presentError:. This is
the error that it is receiving:
NSError "An error occurred while saving." Domain=NSCocoaErrorDomain
Code=134030 UserInfo={
NSLocalizedDescription = "An error occurred while saving.";
NSUnderlyingError = NSError "An error occurred while saving."
Domain=NSCocoaErrorDomain Code=134030 UserInfo={NSUnderlyingException
= no such column: DESC; };
NSUnderlyingException = no such column: DESC;
}
Can anyone tell me why my application is notified of a save error
while opening the file, instead of while saving the file? And more
importantly, what should I check in order to resolve the "no such
column" error?
Thanks in advance.
Regards,
David
