Hi,
On Xcode 4.2 I am getting some error that makes no sense to me and all similar
reports on the web don't seem to apply:
CoreData: FATAL ERROR: The persistent cache of section information does not
match the current configuration. You have illegally mutated the
NSFetchedResultsController's fetch request, its predicate, or its sort
descriptor without either disabling caching or using +deleteCacheWithName:
After I reset the simulator device it works once, I quit the app, launch it and
get the same message. The first launch I did make a fetch, it downloads some
data and puts them into the sqlite core data store, then I call
[self saveContext];
If I don't call saveContext, my data is not saved, and next launch it needs to
download it all over again. If I do save I get aforementioned message.
At the end of the message which also lists all objects in core data, it states:
*** Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason: 'CoreData: FATAL ERROR: The
persistent cache of section information does not match the current
configuration. You have illegally mutated the NSFetchedResultsController's
fetch request, its predicate, or its sort descriptor without either disabling
caching or using +deleteCacheWithName:'
When looking at the documentation on deleteCacheWithName, things make even less
sense to me, because I never cached anything.
Please, could someone help?
Thanks
Alex
