Hello;
As part of a built-in "change notification" facility, I am using "EOObjectStoreCoordinator.invalidateObjectsWithGlobalIDs(..)" with the relevant OSC locked. All use of other editing contexts are locked and unlocked correctly. Occasionally I seem to end up with "disappearing snapshots" where all the values of the snapshot go to NULL -- I can only imagine this would be linked to my use of 'invalidate..'. Other new editing contexts then see the NULLed-out EO and the EO does not seem to re-fault in that instance. When that "corrupted" EO is used in some sort of qualifier, EOF will treat the "primary-key qualifier" as looking for NULL.
Any ideas where to look or has anybody else had this problem and has any pointers?
cheers.
