You usually run into this error when a view tries to draw to a window
that hasn't been displayed at all yet. I don't know if this is the
case for you, since you're talking about swapping views, though - are
you actually swapping out windows when you do this?
Anyway, you can try to make the window non-deferred (you can deselect
the checkbox for that in IB) and see if you get the error then. Doing
that makes the window make a connection to the window server when it's
created rather than when it's first displayed.
If that doesn't help, is the scroll view you're adding the outline
view to part of the view hierarchy when you do that? Maybe there was
a bug in Tiger where the scroll view tried to display the document
view immediately when it's set and if it's not actually part of a
window I suppose this might pop up. That's all just a guess, though.
