Hi,
I am creating a Desktop issue tracking app using core data and the
NSDocument framework - so yes, the Xcode wizard extended
NSPersistentDocument which provides me with an NSManagedObjectContext.
My question is - if I start working in the app, creating issues for
instance ... when I go to actually persist the context I get an error "This
NSPersistentStoreCoordinator has no persistent stores. It cannot perform a
save operation."
So, does this imply that for NSDocument style programming, most folks
aren't 'saving' their context right away? Do we wait for the user to
actually save the document the first time? IE: there is not in memory store
that the Document manages until the user formally saves to the file system?
And does it follow then that on subsequent changes, we formally persist the
context only when the user actually 'Saves'?
Does anyone force the user to 'find' a file location right away, upon
opening a new document, and then persist everything happily in the
background?
I tend to this this is really just a Desktop paradigm question more than
anything else.
Thanks,
-Luther
