In addition to what Allan said, calling -dragPromisedFilesOfTypes:... inside -tableView:writeRows:toPasteborad: is a bad idea and will cause some glitches in your program, like the message queue mysteriously freezing after the call.

If you want to do a file-promise drag to the Finder (or Path Finder, etc.) from an NSTableView, the only way to do this glitch-free is to subclass NSTableView, override -mouseDown: to handle highlighting and click-actions (which you'll have to write yourself, but it isn't as difficult as it sounds), and override -mouseDragged: to call -dragPromisedFilesOfTypes:... or implement periodic event handling, which is more difficult to do.
