Cool - haven't used conditional breakpoints before, and didn't realize
about objc_exception_throw...
That gives me completely different information, but much more useful:
#4 0x97578cba in -[NSAtomicStore(_NSInternalMethods)
_insertNodeIntoMainCache:] ()
#5 0x97578c51 in -[NSAtomicStore(_NSInternalMethods)
_registerCacheNode:] ()
#6 0x9757a51d in -[NSAtomicStore(_NSInternalMethods) _addObject:] ()
#7 0x9757a1a1 in -[NSAtomicStore(_NSInternalMethods)
executeSaveChangesRequest:withContext:] ()
#8 0x9751d4c6 in -[NSPersistentStoreCoordinator(_NSInternalMethods)
executeRequest:withContext:] ()
I guess that means that I'm returning a nil cache node for a managed
object somewhere or something like that, which wouldn't surprise me at
this stage of my coding. With this info, I have a much better idea
what to look for, and where to dig next. Thanks for the quick response.
Gideon
