Ahhh, got it. Probably would have never figured that out on my own,
but now that I see it, it makes sense. Thanks!

Brian,
The first part is a how to that should get you going - followed by a
bit of explanation.
You need to do the following:
The How:
Select the table view itself and inspect its bindings.
You will see three Table Content bindings for the table view:
content
selectionIndexes
sortDescriptors
Bind the content to:
Bind To: Your Array Controller
Controller Key: arrangedObjects
Model Key Path: <leave this blank>
Bind the selectionIndexes to:
Bind To: Your Array Controller
Controller Key: selectionIndexes
Model Key Path: <leave this blank>
Leave sortDescriptors unbound
A little of what's going on:
Typically you only need to bind each table column value binding to the
arranged objects of an array controller. When you do this, behind the
scenes, all three table view content bindings are automatically
'hooked up' for you.
It is only when you need to change these three default content
bindings that you need to visit the table view's bindings.
You can also use this mechanism to do other things with a table view's
bindings (like pull the selection indexes from one array controller,
while displaying the arranged objects of another array controller). I
don't have a particularly good use for that in mind at the moment.
Hope this helps.

I have an NSTableView in a pretty straightforward configuration with
an NSArrayController, with the table columns bound to various
properties of the arrangedObjects key of the controller. My table
columns are set up so that they have no identifier and no sort key,
but when I click on one of the column headers in my app, it still
sorts the table by the key being used to retrieve the values for the
table. I also unchecked the "Editable" checkbox for each column, and
I even programatically set the sortDescriptorPrototype for each
column to nil, but it still sorts the columns when I click on the
headers. How can I completely disable sorting for this table view
while using NSController?
