How to add data from an NSTextField to a Core Data Attribute without having to press Return or Tab after editing the TextField?

问题

I use a sheet with 3 NSTextFields and a Cancel- and OK-Button to edit the attributes of a Core Data Entity. The text entered in the NSTextFields is only updated in the Core Data Entity if i press Tab or Return after writing in the NSTextField or if i focus another NSTextField with the mouse. If i just enter text in an NSTextField and press the OK-Button the entered text is lost.

Is there some attribute i can set in Interface Builder to change this NSTextField behaviour?

The answer in my case is to check the “continuously updates value” option in the NSTextField’s value binding. For other answers to the same problem see: Red Sweater Blog — Stay Responsive: http://www.red-sweater.com/blog/229/stay-responsive
