This suggests the problem is in the line before XXX. Where is 'array' coming from? My *guess* is that it's from a relationship? In which case it's a set, not an array...


The array is coming from a fetch request, which returns an NSArray*.

Here you should be using 'mutableSetValueForKey:', not 'valueForKey:'. <http://developer.apple.com/documentation/Cocoa/Reference/ CoreData_ObjC/Classes/NSManagedObject.html>

Thanks; I realized this and switched it, but then I ran into some other problems... I sent mail about those just now though.


Niko
