I assumed that fullNameAndID would be available among the choices
presented in the bindings pane. That not being the case, I tried
typing it in, and it worked. Yay!

I was happily plugging through the NSPersistentDocument Tutorial,
when I got to the "Creating a Custom Class" chapter. The first
strange thing is that when I created the files, the next
instruction is to change the class name for the Employee entity
from NSManagedObject to Employee, but this had already happened
without me doing anything. That seemed like a good thing. I edited
the class files as instructed, and came to the bit that says in the
nib file, to change the model key path for the pop-up menu binding
in contentValues to fullNameAndID. But the fullNameAndID option is
not there. I tried dragging the Employee.h file into interface
builder, but it didn't help (to start with it crashed IB in fact,
when I had the bindings pane open). Is there a key part to this
that I'm missing, getting IB to recognise that the Employee entity
should be read from the Employee class?
Rather than dragging .h files onto IB like Apple's docs always
suggest, I just use the "Synchronize With Xcode" command under the
File menu in IB. That said, I find that synchronization doesn't
always make new properties appear as options in binding dialogs;
sometimes you just have to type property names in by hand. In
general IB is pretty buggy, including its integration with Xcode, so
don't be surprised when you run into other problems like inspector
sheets which mysteriously blank out when you change a property.
