The application worked perfectly and I tried to make the modification with the CarArrayController.
Since this modification, I get the error message :
2013-09-04 14:43:32.877 CarLot[18620:303] Cannot create BOOL from object ( ) of class _NSControllerArrayProxy 2013-09-04 14:43:32.895 CarLot[18620:303] Cannot create BOOL from object ( ) of class _NSControllerArrayProxy
When I launch the application, and nothing appear (no window).
I got the solution from the site, and It runs perfectly.
I compare between the both, correct some mistake, but the errors remain.
I already read about this subject on the forum, and tried to clean, erase old data and rebuild but without success.
I would appreciate any idea.
But more, I will be very enjoyed if someone can explain me how to debug such “magic”, that are surely TOO magic (at least for me, cause I don’t like when the only solution for any error is to rebuild everytime, everything from scratch)
Many thanks to those who can help.
