Yes, it can literally have an NSArray property, if you use transformable attributes: http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/CoreData/Articles/cdNSAttributes.html%23//apple_ref/doc/uid/TP40001919-SW9 The standard archiving transformer should work fine. (You can also write your own value transformer if you have a reason to, but you'll have to deal with endianness and other architecture-related issues on your own, if you go that route.) _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
