Try this.
Run your application and create a sort on one of the columns (by
clicking in the header). Now add your new items. Regardless of your
sorting, the new items will appear at the end of the table view.
Now. Add the call to rearrangeObjects: and when you add the new item.
It will appear in the correct sort order, depending on the default
values set when creating the new object.
PsuedoCode (blatantly ripped off from Hillegass 3e, P150.)
MyObject *p = [[MyObject alloc] init];
[arrayController addObject:p];
[p release];
// So far this is what you have done - created the object and added it
to the array.
// Now, resort your array depending on the way the user has sorted
columns
[arrayController rearrangeObjects];
// Create an array based on the sorted array.
NSArray *sortedArray = [arrayController arrangedObjects];
// Find index of the object that you just added in this sorted array
int row = [sortedArray indexOfObjectIdenticalTo:p];
// Now we know the position of the item you just added, begin the edit.
[grid editColumn:0 row:row withEvent:nil selected:YES];

I replaced my code with this one:
MyObject *p = [[MyObject alloc] init];
[arrayController addObject:p];
[p release];
[grid editColumn:0 row:[grid selectedRow] withEvent:nil selected:YES];
it works fine, NSTableView selects new row, -editColumn receives
correct row number and starts editing. So, the question is: why do I
need to call -rearrangeObjects? In what cases missing of this call
will lead to problems?

Same goes for -add: ... You'll need to force the array controller to
-rearrangeObjects before asking the tableView to reload. If you're
using Core Data, you'll probably also need to force a -fetch: before
calling -rearrangeObjects, though I don't know for sure.
This forces the array controller to do its thing right then and
there. Of course short-circuiting the mechanism like that can cause
validation problems, so be careful ...
Sorry! I'm not thinking straight ... you will need to directly use
the -addObject: and -insertObject:atArrangedObjectIndex: methods
rather than -insert: or -add: for the above to work. This takes
affect
immediately (but must still be rearranged via -rearrangeObjects).
Also, you need to use the index of the newly-inserted object in the
array controller's -arrangedObjects array, not its contents (so you
get the correct row to edit in the table).
