Hi everyone,
While testing my Palm conduit that uses CoreData, I *think* I have run
into a bug in CoreData, specifically, NSPersistentStoreCoordinator.
All Cocoa/CoreData functionality is located in a bundle which is
loaded at runtime.
Attached below is a snippet of the code:
Are you absolutely sure, that your model fully conforms to your saved
data?
Or did you recently enhanced your model?
Keep in mind, that enhancing a model and loading previously saved
data - based on the previous model - works fine - if using XML.
In case you save your data in other formats - e.g. SQL - CoreData
might not be able to read your data correctly.
I'd propose to read your data using your old model, save it using XML
and reread it using your now model.
Well, just an idea....
