Your description of the problem is a bit fuzzy. Let me nitpick at your description -- it may be that if you straighten out your terminology you'll solve your problem:

It's bound to an array *property* of some object. If the array controller is in the XIB file, it's typically bound to one of File's Owner's properties. > The mutable array resides in a different XIB. Almost certainly not. At least, I hope not. Why would you put a mutable array in a XIB? A mutable array is likely used as the backing store of an array property of an object in your data model (or possibly of a controller object). > The data is displayed as expected, but when I remove an item, although it > does disappear from the table, the > change is not written to disk when the application quits.

We haven't actually located the array yet. You might inadvertently have 2 arrays where you only intend there to be one. > I did some debugging and found that after the items are removed from the > array controller, the underlying array does indeed reflect the removal, > but something happens between there and quitting the application that > brings the removed items back into the array. Another possibility is that you really did put an array into a XIB, which means the *same* array contents will be reloaded from the XIB every time that XIB is loaded. Are you sure "the array" isn't being written correctly to your persistent store? Perhaps it is, but the written value isn't being reloaded next time? > My application also uses an NSPopupButton to display these same items. Is this just additional information, or are you saying there's an issue with the the popup button too? _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
