Do I need to create an instance of the my model object in IB to which I
connect the 'content' of my NSObjectController under the Connections?
Or do I even need an instance of my object and just specify the object
class name in the Attributes section.
I guess that is the problem that I'm having in that I have an instance
of my model object in IB and NSObjectController 'content' under the
Connections is updating this while I create an instance of the same
class in the MyDocument.m. and therefore when I save, I'm not saving
the correct object model.
I have a feeling I'm having things mixed up in here.
Thanks.

in the text fields, non of the model object is getting updated.
As far as I can understand based on Apple's documentation, the model
gets updated through KVC. In IB under the Bindings->Value of the
NSTextField, I enabled 'Continously Updates Value' in order to update
the model. My model is KVC compliant as far as I know in that my
models
implement the <key> and set<Key>: pair. such as empID: and setEmpID: .
you're definitely using an object controller to bind to, rather than
directly to the model?
what type of control is it.. if you can send me (off list - or put it
someplace I can download it) the cleaned code, I'll have a look
Is there something else that I'm missing here to get my views update
my
model object?
no, this should work.
