Ah, yes -- I forgot to say that I'm on Leopard with Xcode 3.
Cheers,

Hi, all,
I want to make my program display a validation error alert when a
string is less than one character long -- I basically want no nil
values. This is in a table view, I should also mention, that
displays records (entities, with corresponding subclasses of
NSManagedObject), that are maintained by an NSArrayController.
I have set the minimum length for this string attribute in my data
model file, but this seems to be ignored in the table view.
Additionally, if I select my entity in the data modeler and use the
New File... managed-object-class creation assistant, even if I check
"Generate validation methods" I get no validation methods -- at all
-- in the created files, despite the requirement of length and
whatnot.
Despite my searches through the documentation (and despite my
possible incorrectness in assuming that the validation-method
generator will do what I want), I have found no way to get the table
view to validate properly. Furthermore, making a -
(BOOL)validateMyTitleAttribute:(id *)ioValue error:(NSError
**)outError in my NSManagedObject subclass does absolutely nothing.
I've been bashing my head against this one for the past few days,
and a search of the archives leads me to think that maybe my project
-- or at least my data model -- is corrupt. The project is so
complicated, however, that I wanted to ask here before undertaking
such a weighty matter.
Many thanks!
Cheers,
Andrew
