In this situation, I've got an existing tree controller (and 
associated view) in some state. The user has chosen to add a new item, 
so my document's -addItem: method has been called. Currently, it's 
implemented like this:

http://pastie.caboo.se/private/x7ln7slfzqyltdx7onj0eq

- (IBAction)
addItem: (id) inSender
{
   NSManagedObject* entity = [NSEntityDescription 
insertNewObjectForEntityForName: @"Item"
                                   inManagedObjectContext: [self managedObjectContext]];
   
   NSArray* curSelection = [mItemsController selectedObjects];
   
   if ([curSelection count] > 0)
   {
       Item* curItem = [curSelection objectAtIndex: 0];
       Destination* curDest = [curItem valueForKey: @"destination"];
       [entity setValue: curDest forKey: @"destination"];
   }
   
   [mItemsController addObject: entity];
}

The problem is, I don't know how to determine to which row that newly-
added object corresponds in the table view. Is there any way? I 
suppose it's the current-selected row, since it's set up to select on 
add. Is there a more elegant way to find out, though (i.e., what if 
adding didn't change the selection).

How does one find the row in the table view corresponding to any given 
instance?

TIA,
