Editing NSTableViews

I was implementing an NSTableView, and I needed a button to add an entry to the table and set it up to be edited.

So I found the method

[categoryTable editColumn:1 row:newRow withEvent:nil select:YES];

And I went about using it. Then I got an error:

Invalid parameter not satisfying: _lastSelectedRow == row

Interesting. So I changed my code to:

[categoryTable selectRow:newRow byExtendingSelection:NO];
[categoryTable editColumn:1 row:newRow withEvent:nil select:YES];

And it works fine. It wasn't that hard to figure out, but:
1) I couldn't find an answer in the mailing list archive, so I wanted to put one there
2) Why doesn't the method just select the row by itself? Why do I need to do that for it?
