I'm such an idiot. :-)
The following method works after receiving a notification (where
'acFoo' is the array controller and 'fooView' is the table view):
- (void)renameFoo:(id)foo
{
int col = [[fooView tableColumns] indexOfObject:columnFooTitle];
int row = [[acFoo arrangedObjects] indexOfObject:foo];
[acFoo setSelectionIndex:row];
[fooView editColumn:col row:row withEvent:nil select:YES];
}
The piece I was missing was [acFoo setSelectionIndex:row] ... It's
probably a good idea to tell your array controller to select the
object in question since it's responsible for managing the table
view's selection too ... ;-)

List:
I have a Core Data app with a table listing "Foo" entity
instances (using bindings). Foo has a -title attribute. When a new
Foo instance is inserted, I would like the table to begin editing
the title column immediately for renaming. The challenge is that
the table is in another nib separate from the document's nib and
new Foo instances are added in an action in my NSDocument subclass.
I've tried catching
NSManagedObjectContextObjectsDidChangeNotification and getting the
inserted objects set, then calling -
editColumn:row:withEvent:select:, but I ended up having to brute-
force updating the table for the row to even be there. This works
randomly. The times it doesn't work, the cell goes into edit mode
for a split second, then another row is selected ... Someone on
cocoadev.com suggested setting a zero-interval timer to get past
the current run loop (worth a try), but I get the same results. I
realize it's all a matter of timing and that I'm probably fighting
the bindings architecture.
What's the best way to accomplish this? I know something similar
to this was discussed here: http://www.cocoabuilder.com/archive/
message/cocoa/2005/9/6/145831
... the fact that I'm doing this in a separate nib seems to make
all the difference as the example given above doesn't work for me.
Any help would be most appreciated.
