Todd -
I'd suspect one of two things:
1) Your store's metadata method isn't returning the same identifier
(ie @"AtomicStore") you're passing to addPersistentStore, so the
coordinator thinks the store isn't what the caller of
addPersistentStore said it would be
2) Your store's metadata method is returning nil, and the coordinator
thinks it isn't actually a store
See the documentation at
http://developer.apple.com/documentation/Cocoa/Conceptual/AtomicStore_Concepts/Articles/asLifecycle.html#//apple_ref/doc/uid/TP40004527-SW1
for what needs to happen when in order to avoid a confused
coordinator. The key detail is: "You must also initialize the
metadata for the store. After
initWithCoordinator:configurationName:url:options:, the coordinator
invokes metadata on the new store; at this point the metadata must be
correct."

Hi All,
Has any one had any luck working with the AutomicStoreSubclass
example. I
need to manage and AtomicStore and thought that I would be able to
use the
AutomicStoreSubclass example as a road-map. When I
addPersistentStoreWithType as follows -
if ([coordinator addPersistentStoreWithType:@"AtomicStore"
configuration:nil URL:url options:storeOptionsDict error:&error])
I get the following error -
Error Domain=NSCocoaErrorDomain Code=134010 UserInfo=0x162240 "The
store
type is inconsistent with the data format."
Anyone know of any gotchas when subclassing NSAtomicStore?
