I’m having trouble with the example on page 114 in the book. Everything seems to match up right up until figure 7.3 Bind Value of Slider to fido.
I’ve selected the check box next to the Bind to and selected AppController. However, under Model Key Path, when i first came in, it was filled in with self and had a red exclamation point. I tried changing it to fido, that changed the exclamation point to black, and i tried building and running the application. It threw a exception as follows:
2011-07-09 21:02:47.709 KVCFun[7188:903] *** Terminating app due to uncaught exception ‘NSInternalInconsistencyException’, reason: ‘Cannot create double from object <_NSControllerObjectProxy: 0x100133fa0> of class _NSControllerObjectProxy’
I’m not clear what i did wrong.
Any assistance would be welcome.
