Re: CoreData migration and file change

[Dan Grassi]

After having read everything I can google I have only progressed to:

"The document “project.xml” has been moved."



I have tried FSExchangeObjects but that did not help.




Any help will be greatly appreciated.

I am doing a manual migration so I do not call configurePersistentStore:... as Miguel suggests but have tried setFileModificationDate as suggested and I only get a slightly better but still confusing message as above. I have not tried moving the migration code to a -writeToURL: or - saveToURL: method and calling that if I need to migrate, surely there is a less convoluted way.

I recently asked a related question on StackOverflow:

The answer should help you out.

I have a CoreData application and am migrating the data store. When the user opens an old store the migration happens automatically creating a new file. The problem is when the user saves the first time after the migration he gets the message: "This document's file has been changed by another

application since you opened or saved it."


avoid this message?

Thanks,
