How to sort smoothly when NSTableColumn's Sort Key is empty

[an0]

I know how to sort items in NSTableView when each NSTableColumn
corresponds to a property of the item object.
But what if there is only one NSTableColumn and it is just mapped to
the item object itself instead of a property of it?
I set the Selector to compare: and leave the Sort Key to empty for
the NSTableColumn in Interface Builder. It seems items can be sorted
once in such a case but the order can not be reverted by clicking the
column header again.
And the NSTableView's sortDescriptors are found cumulated instead of
changed by NSLog in dataSource's tableView:sortDescriptorsDidChange:
method.
What is the right configuration for such a case then?

Hmm, could be a bug. Try giving your object a readonly property that
returns self, e.g.:

- (id)identity { return self; }

And bind to 'identity' rather than leaving the sort key empty. Let us
know what happens!
