I believe I've found the answer to my drag and drop problem: http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/CoreData/Articles/cdUsingMOs.html
Drag and Drop is just a glorified copy/paste and on that web page I found: "If you just want to copy a managed object’s attributes, then in many cases the best strategy may be in the copy operation to create a dictionary (property list) representation of a managed object, then in the paste operation to create a new managed object and populate it using the dictionary." Also: "It is difficult to solve the problem of copying, or supporting copy and paste, in a generic way for managed objects. You need to determine on a case-by-case basis what properties of a managed object you actually want to copy." _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
