Disabling sorting in table with bindings, popup menu, revisited (and with sample)

Greetings,

I'm fairly new to bindings, and overall things have
been coming together quite well, but I'm stuck on
something now, and I can't seem to get past it. I need
to disable the sorting in a table with bindings and a
popup menu column. I've read the "James Dempsey"
suggestion in the archives, and while that does
disable sorting, it breaks the table itself. When the
table is loaded, I get the following printed to the
log:

*** -[_NSControllerArrayProxy firstIndex]: selector
not recognized

Then, when I click on any row in the table, I get:

*** -[NSMutableIndexSet
_valueForKeyPath:ofObjectAtIndex:]: selector not
recognized

printed repeatedly in the log. I've tried a bunch of
things, searched the list archives (where I found this
exact question asked before, but not really answered)
and still can't get sorting to be disabled without
problems. Because it's probably easier to look at
bindings in Interface Builder, the sample project is
available here:

I was hoping with a sample project someone could take
a look at how I set things up and offer a suggestion
as to what I've done wrong. Any help would be greatly
appreciated.

-- Michael
