Hi, I am getting occasional reports of an exception from users of my software, but they are not able to reproduce it, and nor am I.
I have a sheet which has an NSCollectionView on it and a couple of buttons and a slider. The NIB also instantiates an array controller which is used as the content for the collection view. This is the exception I get: *** NSMapInsertKnownAbsent(): attempt to insert notAKeyMarker 0 CoreFoundation 0x00007fff896a9fc6 __exceptionPreprocess + 198 1 libobjc.A.dylib 0x00007fff855ced5e objc_exception_throw + 43 2 CoreFoundation 0x00007fff896a9dfa +[NSException raise:format:arguments:] + 106 3 CoreFoundation 0x00007fff896a9d84 +[NSException raise:format:] + 116 4 Foundation 0x00007fff890f67bc -[NSClassicMapTable setItem:forKnownAbsentKey:] + 74 5 OmniAppKit 0x000000010051f008 -[OAApplication beginSheet:modalForWindow:modalDelegate:didEndSelector:contextInfo:] + 184 I do not instantiate an NSClassicMapTable explicitly in my code, but am assuming that either the array controller or the collection view uses such things. I have never been able to reproduce the problem myself, either in a test environment or anywhere else either on 10/6 or 10.7 (users have reported it on both operating system versions). If anyone has any suggestions as to where to look for this, I'd be very grateful.
