If your outline's data is being populated from an NSTreeController
then the fetch isn't happening until the next iteration of the event
loop. If I understand it correctly this is done so that it can present
any errors as a sheet on your window.
Try delaying your call to expandItem: in your awakeFromNib.
- (void)expandAllItems {
[outline expandItem:nil expandChildren:YES];
}
- (void)awakeFromNib {
/* snip */
[self performSelector:@selector(expandAllItems) withObject:nil
afterDelay:0.0];
}
I believe that should work.

I've trolled through the archives looking for help on this, but I
can't seem to find anything that quite works. I'm trying to set it
up such that an NSOutlineView starts out fully expanded. In the
delegate, I have the following code:
- (void)awakeFromNib
{
[outline expandItem:nil expandChildren:YES];
}
I feel like I'm missing something rather obvious, since the same
code works when it's attached to a button. Is there a better place
to put it than in awakeFromNib:?
Thank you so much both for your help and your patience.
Peace,
Andy
