Is that how it is supposed to be done?
Currently I have an object with two values (one for each column) that
has an instance for each line in the NSTableView. Each of those
instances is stored in an array that the ArrayController is bound too.
And the array is created in my controller class.
So I am not sure how I would use willChangeValueForKey or what the
"key" is.
Do I need to change the data model?
Do I need a new class that has the array in it?
I am rather confused and have not found an example online that has a
programatically created data model that I have been able to follow and
understand, given my newbie-ness.
Bindings seem to be a great way to do stuff, but the limited amount of
documentation and examples is making it hard for this beginner to get
ones head around it all.

you send willChangeValueForKey: etc. to the content object containing
the array, right? And which key?
Kane, I ran into the same problems too, in ObjC and in Java...
and the most difficult question: how is this done in Cocoa for Java?
Can it be done at all?!?
