Ok, I see. The main thing is that now it works and I can setup the
bindings in IB instead of programatically which is another bonus...
Thanks for all the information,

Thanks Keary, this works
I have the following core data model:

On my form I want the user to select the desired project from the
table and then based on that selection, I want to display all
measurements (for all sessions) for that project. I have two array

Hi, thanks for suggestion - definitely worth remembering it.
Yesterday evening I was playing a bit more with array controllers and
I figured it out - I use intermediate array controller for sessions
and bindings like this:

I have 1:N relationship between Project and Measurement entities. I

Thanks for pointing this out. I use fetch request to get the data, so
I thought this should work. Digging even further I realized my

model and now the fetching works.

Hi Raphael and Cathy - thanks both for your replies.

(although the objects are not released because dealloc is not
called...) - in fact my code is almoust identical to the one shown

I haven't though of this. I solved the issue though, through Cathy's
proposal, by adding removeObservations method to my view controller
base class and call it from my NSWindowController implementation. Now
the dealloc is called as expected.
In one of my nibs I do use the file's owner as a

Hi all
I'm (again) banging my head with a single window, multiple views app
using core data. Each of my view is implemented within it's own NIB
and handled by a NSViewController subclass. The views share the same
data from the same MOC. Using the following core data model I cannot

How are you binding the "item" array controller? It has to be bound
to the group list array controller or to a property of the app
delegate that depends on its selection.
In MainMenu.nib the two array controllers are bound:
GroupsController:
- managed object context -> AppController.managedO
n 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?
