This is probably just lack of experience with the NSOutlineView but I can't see a way to do this. I have a NSOutlineView (implemented with the excellent PXSourceList) with an add button that is totally functional in the aspect that I save/write/insert/delete rows correctly. I do not use a NSTreeController, and I don't use bindings. I add the entity using the following code:

- (void)addEntity:(NSNotification *)notification {
    // Create the core data representation, and add it as a child to the parent node
    UABaseNode *node = [[UAModelController defaultModelController] createBaseNode];
    [sourceList reloadData];
    for (int i = 0; i < [sourceList numberOfRows]; i++) {
        if (node == [sourceList itemAtRow:i]) {
            [sourceList selectRowIndexes:[NSIndexSet indexSetWithIndex:i] byExtendingSelection:NO];
            [sourceList editColumn:0 row:i withEvent:nil select:NO];
            break;
        }
    }
}

When the add button is pressed, a new row is inserted like this:

If I click away, then select the row and press enter to edit it, it now looks like this:

My question is: How can I programmatically get the same state (focus, selected, highlighted) the first time, to make the user experience better?
