Hi James,
today I read your mail:
I ran into a problem with the reference some time ago. I have solved
it by posting/observing a notification with the reference as the only
object in the userInfo dict.. That works fine and assures, that the
reference can be determined exactly. The only pro
So, I decided to get rid of the NSArrayController, since it was driving me
slightly crazy, and just do this manually. I've got the table **appearing** as
I'd like it to, but I can't change the selection. There are 3 columns: 1)
string, 2) NSPopUpButtonCell for MIDI ports, and 3) NSPopUpButtonCel
oh jeez... This is making me crazy. For some reason, my NSArrayController
appears to be calling "count" on MIDIInstrument objects. No idea why. I could
see it calling count on the array it's controlling, but not an object in that
array. Has anyone come across this problem?
I have a MIDI_Instru
okay, going slightly nuts. I've implemented my MIDI_Instrument_Controller
object, and hooked it up to my table view, but it's complaining about
implementing numberOrRowsInTableView and
tableView:objectValueForTableColumn:row:. Fine, except that I very definitely
have implemented them. I tried c

okay, there seems to be a big design flaw here... I think this will all be
simpler if I have a separate MIDI_Instrument_Controller, loaded in the nib,
which can deal with the table and the Central_MIDI_Controller. Then I'll let
the NSArrayController deal with instances of the MIDIInstrument itse
ugh...

Yes, this is basically what I've done, and it does seem to work...

Hey Mark,
Thanks for this, but it points out one confusion i have. If I thought it would
be fine to just have MIDIInstrument in the nib, everything would be simple. But
my (mis)understanding was that putting the MIDIInstrument in the nib would only
apply to that single instance. Is that not cor

Sure

okay, so I kind of hacked around it. I gave my AppController (which is a
delegate of File's Owner) an outlet for the Central_MIDI_Controller, and hooked
that up in IB. Then I also gave the AppController an accessor for
"midiController", that returns the reference to Central_MIDI_Controller

You can add an outlet to your app controller object pointing to that controller
object, and then add an access
