Not key value coding-compliant


When I want to add a new department, I get this error :

I can read and understand the words, but what did I miss ? what I have to do ?

I suppose this has to do with binding, but is there any way to get a list of the bindings, just the same as we have in the book … :slight_smile:)
I think it’s will be a good tool !


It may be the same trouble as my case. I made a mistake that in “MyDocument.xcdatamodeld” one of the Relationships of Department entity “employees” was written “employee”.
