Sorry, I'm on a 'digest' mail subscription to the list, so I missed =20
your post, Kimura-San.

Great, thanks to both of you, things are now working, but not =20
*exactly* as you mention.
In my 'awakeFromInsert' method, why does

	employeeID =3D 123		# not self.employeeID
	puts employeeID
	puts self

reply '123' for employeeID, but NOT update self :
<Employee: 0x520d00> (entity: Employee; id: 0x523ed0 <x-coredata:///=20
Employee/tFC895DBA-B5E8-4764-B296-32FA106D280E> ; data: {
     department =3D nil;
     directReports =3D ();
     employeeID =3D nil;			# not updated
     firstName =3D First;
     lastName =3D Last;
     manager =3D nil;
     salary =3D 0;
})

when
	self.employeeID =3D 123	# using self.employeeID
	puts employeeID
	puts self
replies '123' for employeeID AND updates CORRECTLY self ?
<Employee: 0x520d00> (entity: Employee; id: 0x523ed0 <x-coredata:///=20
Employee/tFC895DBA-B5E8-4764-B296-32FA106D280E> ; data: {
     department =3D nil;
     directReports =3D ();
     employeeID =3D 123;			# updated correctly
     firstName =3D First;
     lastName =3D Last;
     manager =3D nil;
     salary =3D 0;
})

Thanks for your help. Being rather newbie on Cocoa/CoreData and =20
RubyCocoa, I do not know whether I am using incorrectly the former or =20=

the latter.

Cheers,
