If you focus the cell again and type, does editing end after _every_ keystroke? Or can you continue editing properly after that? Where does focus go? Is the table view focused? Or is nothing in the window focused? For example, if you type an up- or down-arrow key, does it select rows in the table view? > Has anyone else hit this issue and solved it?

Is the array controller set to rearrange its contents automatically based on sort descriptors? Does the table column's value binding have Continuously Updates Value enabled? If so and you change that, does the problem go away? The table view will be the text cell's delegate and will be called for the delegate methods described in the NSControlTextEditingDelegate protocol as well as those described in NSControl. Try using a custom subclass of NSTableView (if you're not already) and overriding -controlTextDidEndEditing: and -control:textShouldEndEditing: to log [NSThread callStackSymbols] and call through to super (if the static superclass's instances respond to those methods, i.e. [NSTableView instancesRespondToSelector:_cmd]). The stack trace should give you some idea of what's responsible for removing focus from the cell. If the whole table view is losing focus, you could do the same with -resignFirstResponder. Try to reproduce the problem in a new project, adding/changing as little as possible to get it to reproduce. If you can, try sharing that with us.
