I don't see anywhere in your code where you add a new row to the  
NSTableView. The error you're seeing occurs because the row being  
asked for doesn't exist.

Is your NSTableView populated using a datasource or bindings?

With a datasource, I think you may have to add a prototype element to  
the datasource and call tableView.reloadData. After that, you can  
hopefully select the new row.

With bindings, you add a new row by going through the NSTableView's  
NSArrayController (you can bind insert: directly to a button's action).

Can you give an example of the PyObjC code that works?

Cheers,
