Howdy all, Hopefully this is a ridiculously simple question with a ridiculously simple answer, but I just haven't been able to find it.
I have a document based CoreData app and I want to change the store type of the file. So it previously saved as XML, and I now want those docs to save as SQLite. But, i still want to be able to view the XML based docs, just require the user to re-save as SQLite. There are no changes to the model. All the data looks and is structured the same. So I added a new document type with a SQLite store and a different doctype and set it to editor. I left the old doc available as an editable document. At this point, I can open up an XML document, edit it, save it, and then re-save it as a SQLite document w/o any issues. The problem is when I flip the XML doc from Editor -> Viewer. I can no longer save it in place (as expected), but whenever I try to save it as the SQLite doc, the app crashes. I know that it's bombing somewhere inside NSPersistentDocument's writeToURL:ofType:forSaveOperation:originalContentsURL:error:, but beyond that am lost. In the save document window, the doc type is correctly set to the new extension for the SQLite store. Again, when the app is set to editor for XML, I can re-save the doc as SQLite. When I can only view the XML docs, re-saving as SQLite crashes. I've tried all sorts of incantations with PersistentStoreCoordinator's migratePersistentStore:toURL:options:withType:error:, addPersistentStoreForURL:, removePersistentStore:error: and have gotten nowhere. I've also tried explicitly setting the document's fileType, but have had no luck. Clearly, this is something that should be easy, since the app handles it automatically when I can edit the XML docs. So what do I need to do?
