I'd really like to see the final code for this. As I have lamented before...
<http://www.cocoabuilder.com/archive/message/cocoa/2004/9/2/116428>
...I've been stymied by the fact that even shouldSelectRow: arrives too late
or is even not sent under certain circumstances. I am forced to store the
selection state every time it changes, and use tableViewSelectionDidChange
to undo whatever the user did - visibly, and after the fact - if I
disapprove of it. If you've solved the problem, I'd like to see the
solution. Thanks! m.
