Hi,
Recently, NSNotificationCenter changed to always create its own
NSNotification (GSNotification in practice) object. This broke using
custom sub-classes of NSNotificaion to send extra information outside
the userInfo dictionary, and caused all apps to crash. The text about
sub-classes in:
http://developer.apple.com/techpubs/macosx/Cocoa/Reference/Foundation/ObjC_classic/
Classes/NSNotification.html
suggests that you're supposed to be able to do this.
Thanks ... bug crept in when changing our implementation to be a class
cluster
(like MacOS-X) and to handle retain/release/autorelease sequencing like
the
MacOS-X implementation (required for some uses of notification posting
within
dealloc methods of objects).
Should be fixed now in CVS.
