Re: Core Data _NSFaultingMutableSet Exception
Do you have an old, unfixed version of your nib in version control somewhere? (The answer should be yes; if not, you might want to reconsider your approach to version control for the sake of your own sanity.) If so, do the same thing you did, confirm that it causes the same problem, and send the old and new versions of the nib off to Apple in a bug. There have been instances of this before, where objects simply weren't written to anticipate a property changing more than once in the lifespan of that object. These cases are definitely bugs. --Kyle Sluder On Dec 22, 2009, at 7:56 AM, Gerriet M.

Core Data _NSFaultingMutableSet Exception
Core Data model with two entities: A and B. A has property aValue and a relation theBs to one or more Bs. B has a property bValue. Two NSTableViews (tabelView1 and tableView2 ) with each controlled by an NSArrayController (arrayController1 and arrayController2). Everything works fine when I send: [ arrayController1 setFilterPredicate: aValue BEGINSWITH[n] a]; [ arrayController2 setFilterPredicate: aValue containsInside: a]; (Well, I do send real predicates, but they contain the strings shown above. containsInside: is declared in a category on NSString) But when I use: [ arrayController1 setFilterPredicate: aValue BEGINSWITH[n] a AND ANY theBs.bValue == xx]; I get an exeption: HIToolbox: ignoring exception '[_NSFaultingMutableSet 0x1001f5d00 addObserver:forKeyPath:options:context:] is not supported. Key path: bValue' that raised inside Carbon event dispatch When later I reset the filterPredicates back to the simple (working) mode, I get another exception: HIToolbox: ignoring exception 'Cannot remove an observer arrayController1 for the key path theBs.bValue from A-entity 0x114f02a10 because it is not registered as an observer.' that raised inside Carbon event dispatch 1. This is a Cocoa document based app, using Core Data. Why this Carbon event dispatch. And who is HIToolbox? 2. I have an identical app, which works perfectly. (Obviously these two apps are NOT identical, but I really cannot find any differences. I tried to remove all changes I made to the newer app, but the exception remains). I spend now more than a day chasing this exception. Any hints would be most welcome. 10.6.2.

Don't worry about where it came from -- it came from the bowels of the Mac OS.

So all this means is that an exception didn't get caught until it reached the Carbon layers. I don't think such exceptions were previously logged before 10.6, though they undoubtedly did occur. You need to concentrate on where the exception came from and stop it from being raised, not where it ended up getting caught. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
