I have a document based Core Data app.
MyDocument.nib contains an NSTableView bound to an NSArrayController.
There also are + and - buttons, which send add: resp. remove: to the
array controller.
SomeEntity.m (subclass of NSManagedObject) implements validateForInsert:,
validateForUpdate: and
I think you misunderstand what -validateForInsert: and friends are for. They
use insert here in the sense of inserting into the persistent store.
So -validateForInsert: is called the first time the object is added to the
store (calling -[NSManagedObjectContext save:] ). From then on,
i have a bunch of methods that will call one method. currently, i'm
passing a string object so the called method will know which method
had called it, and complete the proper task based on the method that
called it.
instead of creating strings and passing them, is it possible to pass
the method

Good programming practice
Did you set a breakpoint on the data source methods?
Please reread about memory management. Your code is full of wrong retains.
Why is segmentDict a global variable? You just assign to it but never release
it.
segmentIndustry is a class and should be named with a capital S.

Hi,
I have an application that persists its data using core data.
It uses an NSOperation to download new versions of the data asynchronously.
This NSOperation uses its own MOC (moc2) (as opposed to the MOC (moc1) used
in the main thread, which is used by the UI). Both MOCs share

I think that you want to implement the awakeFrom* methods on NSManagedObject
rather than the validate* methods for your purposes.
But as for them never getting called, make sure that your NSArrayController
bindings are correct. Specifically that it's mapped to your NSManagedObject
subclass.

So, so far so good.

You can pass the hidden parameter _cmd which is of type SEL you can then use
@selector(selector_name) to do your test, this whole thing you are doing
sounds really strange, it would be good to see what you are doing to find a
better approach. based on what little information your are giving us

Thanks for your help.

are not reached at all.
I did not give you all the methods in my code (it is too lengthy). segmentDict

Good programming practice encourages the idea that
functions and methods are complete in and of themselves, and
are invariant under different calling conditions.

Sounds like bad design ;)
a dealloc method takes care of releasing the arrays and dictionary.

Then you must consider the possibility that your table view has a nil

Hey all, quick question. How you do pass around protocol references?
I'm looking to do something like what NSDistantObject uses to set a
