I fail to see how I can get to the outline view from the data source.
You can always add an outlet(s) from your data source to the outline
views. If the data source for an outline is changing dynamically, you
can always update the data source outlets at the same time. It's more
bookkeeping, so it becomes a question of deciding which path will be
simplest. You may decide that subclassing is the easiest route.
Hard to say more without a clearer idea of the end goal...
Note that the data source can be used to serve data to both outline
views, or to only one, and sometimes none at all. The data source
for an outline view can be changed at runtime.
So I see no way of getting to the outline view unless I subclass it
and then in menuNeedsUpdate I can call [ self clickedRow ] or
whatnot. I'd rather not subclass it if there's another way tho.

As I understand it (simplified), you have two outline views, and
each has its own context menu. This part can be done completely in
IB. In addition, you want to do [something] before either menu is
displayed, right? Now, you already have a data source/delegate for
the outline views - why not implement the menu delegate method(s)
in the outline view delegate as well? I.e. - have one delegate
managing both outline views and menus.
Or is there something else you want to do?

This is what I have done except I have only one menu and hooked up
all outline views to this menu. Having a separate menu for each is
a better idea. Don't know what I was thinking there...
So I need to subclass NSOutlineView then, implement the
menuNeedsUpdate method in my subclass and set it as the menu's
delegate?

I might be misunderstanding what you're trying to do, but have
you considering creating the menus in IB and setting the outline
views' menu outlet to the appropriate menus? Then, the right menu
will show for each outline without any code on your part. If you
need to modify either of the menus before they display, you can
implement the NSMenu delegate method - (void)menuNeedsUpdate:
(NSMenu *)menu.

I have a number of outline views and want to add contextual menu
support to them. The data sources are set as delegates for the
outline views and two outline views could use the same data
source.
The problem is I can't find a way to get the outline view I
right-clicked in when in - (void) menuNeedsUpdate: (NSMenu*) menu
The menu update method is in the data source.
Any ideas on how to know which one of the outline views I'm
about to display the menu for?
