I know it's very lame to reply to my own post asking again for help
because there must have been something in my original post that made
it unworthy of getting help the first time, but it's been two more
days of me trying every possible conceivable combination to be able
to bind an NSMatrix of checkboxes to an instance variable of objects
in an array without success.
All dignity is gone, I'm a total loser and I'm now officially begging.

I feel so stupid and frustrated because it seems like it takes me 2

especially these ones with the "content" "contentObjects" and
"contentValues" that drive me crazy. The documentation just makes
my head spin.
I want to bind an array to an NSMatrix of checkboxes. When I click
one of the checkboxes, I want the corresponding object in the array
to get updated. I can bind a single int to a single checkbox no
problem, but I am totally stumped by NSMatrix Bindings. Am I
supposed to make an array of NSNumber objects?
The NSMatrix Bindings docs say:
content
An NSArrayController instance that provides the content of the
NSMatrix.
So that is what I'm using. I have "arrangedObjects [testController
(NSArrayController)]" bound. But then it says that binding is read
only, so I go ahead and set up a binding for:
contentObjects
An array of objects that are (sic) returned by selectedObject or
selectedObjects in place of the corresponding content object.
If content is not bound, the contentObjects binding is not available.
Here I start to go nuts. What does selectedObject have to do with it?
Does anyone have a sample or can describe how to do this binding?
Or am I totally missing the fact that this binding is not possible?
Thank you
