Jerry, thank you for your response. Your solution is actually what I am currently doing =) Like I state in my e-mail, I'm observing the content array of the NSArrayController, and am getting notifications perfectly fine. I'm just wondering if there's a better way to do all this since I'm losing some of the free functionality provided by NSArrayController + Core Data. One of the biggest things I'm losing out on is the free loading of documents in to my application. The NSArrayController does a fetch and populates arrangedObjects, but this brings me back to the original problem of not being able to access the objects that were added to the array controller. Perhaps I should give up the free functionality that Core Data is providing me and implement this functionality manually?_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
