Thanks Keary, this works, however it requires that the same binding
is repeated in each nib where the same list should be handled (some
views may only need to show it while others can also modify it). I
was thinking of creating a "master" set of controllers in the main
nib, then bind the "slave" controllers in particular view nib file
to the values from the corresponding master controller. Is that
possible, or is it not how bindings should be used?
It is possible, and is within the domain of issues that bindings help
solve, but I don't see how it would change having multiple repeated
bindings. In fact, it adds a useless layer onto the problem.

GroupItemsController:

The question marks are what I'm missing - if I don't bind to
anything, then the array controller will simply show all items for
all groups, however I want to bind this to the
GroupItemsController from the MainMenu.nib (it is accessible
through the Application.delegate, but I don't know how to bind it
in order to show only the items selected by the group in
GroupsView.nib...
Have you tried Application.delegate.GroupController.selection.items
(the last key os whatever relationship you need to use)?
