I have the checkbox value bound to an NSInteger instance in a class which is in an array bound as the content to an array controller. When the program starts the column is filled with 16 rows and the checkbox is set to off. Other columns with bindings seem to work OK, but the checkbox column gives the error > > Cannot create BOOL from object ( > 0, > 0, > 0, > 0, > 0, > 0, > 0, > 0, > 0, > 0, > 0, > 0, > 0, > 0, > 0, > 0 >) of class NSCFArray > >This column is not bound to a core data managed object. The other columns are.

When faced with a problem like this, make a tiny new project that implements the simplest aspect of the problem. In this case, you'd make a one-column table and bind the column in such a way as to do what you want. That way, you eliminate the element of "mixing", and you will soon see whether it is the "mixing" or some other issue with how the binding is set up that is causing the difficulty. m. -- matt neuburg, phd = m...@tidbits.com, <http://www.tidbits.com/matt/> A fool + a tool + an autorelease pool = cool!
