Well, FWIW it was 100% true because I deliberately specified "in a persistent store". :) A file wrapper (or, *shudder*, a resource fork) might be a solution for a determined person, but it would be far easier to embed the data in a Core Data property. Assuming that this is what the OP is asking about to begin with. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
