I'm stumped. In my model I have a Entry entity and a Reference
entity. The Entry-Reference relationship is to-many, while the
inverse is to-one. On the Entry side, the relationship's name is
"references" and on the Reference side, the relationship's name is
"entry". I've checked the setup a dozen times.
Both entities use their own NSManagedObject subclasses. I've checked
this setup a number of times, and I'm certain I am following Core
Data subclassing guidelines.
Because the Reference entity includes an "id" property which the
entry uses to keep track of it, I've added a method to the Entry
class which creates References:
For entityName I'm passing in the string "Reference." Everything
seems to work. I can set properties on the Reference, display it in
an NSTableView using bindings, etc.
However, there are parts of the code which access the Entry when the
Reference has been supplied. Every time this code is called, the
valueForKey method returns an NSCFNumber instead of the Entry with
which the Reference is associated. The code is simple enough:
That anEntry variable is *always* a nNSCFNumber. Asking for any of
attributes (title, icon, etc) returns the correct value. I'm
completely stumped. The data model is correctly setup, I'm sure of
it. The subclasses are proper, I'm sure as well. Why does
valueForKey:@"entry" always return a number then when it is mapped to
the Entry entity?
Recently, I did rename the Reference entity from "Resource," going
through all the code and changing the necessary parts, as well as
everything in the Nib files. I originally thought that could be
related to the problem, but then I've completely re-written this part
of the data model, even using different names for the entities and
relationships. The problem remains the same. Short of trashing the
data model file and rebuilding it from scratch, I don't know what to do.
Any direction would be appreciated.
