Greetings:
I'm having a tough time tracking down the source of a 'selector not
recognized' error:
*** -[NSArrayController presentError:]: selector not recognized [self
= 0x388df20]
*** NSRunLoop ignoring exception '*** -[NSArrayController
presentError:]:
selector not recognized [self = 0x388df20]' that raised during
posting of delayed perform with target 38c49b0 and selector
'invokeWithTarget:'
============
This happens soon after startup of the application.
I tracked it down to a specific simple NSManagedObject. If I change
the binding to a different MO, the error disappears.
The MO suspect is merely bound to an NSArrayController via attribute
and the MOC's parameter binding.
Nothing else; not connected to any GUI at present.
I've tried:
1) Rebuilding the project piece-by-piece from an earlier backup;
2) Replacing the current NSArrayController with a new one;
3) Remove nearly all the elements within the MO;
4) Change the MO's NSManagedObject class to a customized class with
attribute accessors;
5) Disconnected any NSNotifications associated with values within the
MO.
Nothing helps.
I didn't introduce any selector; it's essentially a plain-vanilla MO.
Question:
1) How can I determine the EXACT selector the run-time is complaining
about?
Any ideas?
Ric.
