NSNotificationCenter problem

[Andreas Höschler]

Hi all,

I have a very weird problem that causes me tearing my hair out. For the 
first time in my life something works beautifully well under GNUstep 
but not at all under MacOSX. And I have no idea why. I do

   [[NSNotificationCenter defaultCenter] addObserver:self 
selector:@selector(storeDidRevert:) 
name:SOInvalidatedAllObjectsInStoreNotification object:editingContext];

   [[NSNotificationCenter defaultCenter] 
postNotificationName:SOInvalidatedAllObjectsInStoreNotification 
object:editingContext];

- (void)storeDidRevert:(NSNotification *)notification
{
   NSLog(@"storeDidRevert...");
}

This works initially, but when I trigger

   [[NSNotificationCenter defaultCenter] 
postNotificationName:SOInvalidatedAllObjectsInStoreNotification 
object:editingContext];

again, storeDidRevert: is not called anymore (only under MacOSX). My 
first guess was there must be an removeObserver: statement anywhere, 
but there is none. And I use exactly the same code on GNUstep where my 
code works perfectly! :-(

Any idea how this can be tracked done efficiently (with gdb)? Under 
GNUstep I would raise an exception in removeObserver if 
notificationName is SOInvalidatedAllObjectsInStoreNotification but on 
MacOSX I cannot simply alter and recompile the code of 
NSNotificationCenter.

Hints are greatly appreciated!

Thanks,

  Andreas
