NSManagedObjectContext Multiple Selection Error

I have a Core Data app in development and I'm experiencing a strange
error saving a managed object context to its store whenever I make a
change to a multiple selection of an attribute in a table view that
is connected to an array controller. Changes to a single selection of
an attribute work without a problem. It seems as if the MOC is not
committing the changes for a multiple selection and generates a
pointer error. I have tried to force it to commit changes with -
commitEditing, but this doesn't seem to help. I'm periodically
sending the [MOC save] inside an NSTimer. Once this error occurs, the
MOC also cannot be saved manually.

selector not recognized [self = 0x34f020]
2006-10-05 19:05:39.211 NEM-SFN[7304] *** NSTimer discarding
exception '*** -[NSCFNumber length]: selector not recognized [self =
0x34f020]' that raised during firing of timer with target 355e50 and
selector 'runModel'
The line throwing the error is:
[[self managedObjectContext] save:NULL];
Any suggestions?
