Starting earlier today, I started getting the following error in my
software.
2008-04-14 17:59:41.535 WineCellar[4928:10b] Cannot remove an observer
<WineArrayController 0x25a450> for the key path "wineType.name" from
<Wine 0x6c55170>, most likely because the value for the key "wineType"
has changed without an appropriate KVO notification being sent. Check
the KVO-compliance of the Wine class.
I haven't changed anything significant (well at least I don't think I
did) and I definitely have not been messing around with the
WineArrayController and/or the Wine classes. I can't figure out how to
track this error down -- I've tried a number of things including
putting a removeObserver:forKeyPath method in the array controller so
I could look at the back trace and I've also put in enter and exit
debug messages in a large portion of the code. Still the error seems
to come from nowhere and I am stumped as to how I might find what the
root cause of the problem is.
Does anyone have any suggestions as to how to track down this type of
error.
Thanks very much.
