Namaste! Thank you for your answer.
I did some digging and found that the real issue is the call for processPendingChanges that apparently is called via the executeFetch. According to what I read this is standard behavior. So, I'd have to say it isn't a "bug" in this case. Relative to the performSelector you suggested, I am not able to locate a sample that shows how to use that in conjunction with awakeFromFetch in order to do what I'd like. Do you know of a sample somewhere that shows such use? Also, would a better solution be to create a custom -addEntity method that fetches the next value, then calls the NSArrayController's add (or a more relevant -add), then updates the relevant attribute? To me it makes far more sense to put such stuff in the awakeFromInsert, so I'd consider the above a kludge, however, if that, in this case, is what needs doing... Many thanks in advance!
