I posted a question yesterday, and some of the responses were very
helpful (thanks, by the way), but also showed me I didn't fully
understand what I needed to ask. After several more hours of
exploration last night, I think I have a grasp on my real question. My
problem comes down to this (I think): when no item is selected in the
an outline view, the tree controller instance that it is bound to
still returns an array for selectedObjects with objects in it, and
when binding the content set of another controller to that tree
controller's selection key, the other controller shows data as if
something were still selected in the tree controller.
Essentially, I have three views - the main NSOutlineView with a tree
controller, and then I have two subordinate views, each of which shows
items relative to the selected root object in the main NSOutlineView,
one shows them hierarchically in an NSOutlineView, and the other shows
a flat, alphabetized list of the same objects using an NSTableView.
There is a different association from the root object for each of
these views. Both of these subordinate views have their own
controllers, and they work just fine, except that when the main
NSOutlineView has nothing selected, but previously did, the two
subordinate views should show nothing, but they seem to show the data
from the last selection; the Tree Controller doesn't seem to be aware
that there is nothing selected in the outline view bound to it.
Am I, perhaps, doing something wrong here, or is there some setting I
can set to cause the tree controller to get informed by the outline
view when nothing is selected? If not, is there some accepted way of
doing this? Or have I stumbled across an honest-to-goodness bug and
should file a bug report?
Thanks much,
Jeff
