The breakthrough is that STV will automatically bind this added control to one of your object's properties. Have you watched the video tutorials? (Core Data video tutorial for example: http://www.sensiblecocoa.com/video-tutorials/watch/7/coredat...)

This scheme has enabled our customers to cut their development time by one tenth in some cases. You can see some of our customer testimonials here: http://www.sensiblecocoa.com/buy-now.html

Thanks again!
