Thanks for the suggestion Scott.
For the meantime, that's what I've done - I added a method to my main
app delegate that passes back very simple sort descriptors -
basically just the key to sort on and to sort Ascending. Or is there
something else I should point the arraycontroller sort descriptors at?
I was hoping to do this without adding any code. Is there a reason
that setting the key and method do the column in IB doesn't work for
nsmanagedobjects like it does for custom model objects? (Hillegass'
book has an example of this - a custom model object, sets the sort
key and method in IB and it will sort on its own).

Hello,
I've got an NSArrayController with a predicate set in the
predicate editor so that the NSArrayController only shows a subset
of my NSManagedObjects.
I have an NSTableView bound to the NSArrayController. I have two
columns showing. I would like to sort of the rows showing in the
TableView based on one of the keys in the NSManagedObjects. How do
I do this?
NSTableColumn's Attributes page lets me set a sort key. I entered
the name of the key I wanted to sort on there, but no luck. Do I
need to produce sortDescriptors somewhere in my chain?
If you set the sortDescriptors on your array controller, you'll
be all set.
