You need to post objectDidBeginEditing: and objectDidEndEditing:
(see NSController docs for more) to the object controller.
Do this from the model setFoo: methods.
No! You should *not* do this. The documentation is very clear about
this. You should change attributes in a key-value observing
compliant manner. Typically this simply means using accessor methods
that follow standard naming conventions (see <http://
developer.apple.com/documentation/Cocoa/Conceptual/KeyValueCoding/
index.html> and in particular <http://developer.apple.com/
documentation/Cocoa/Conceptual/KeyValueCoding/Concepts/
AccessorConventions.html>).
The NSEditorRegistration protocol (which contains the methods
objectDidBeginEditing: and objectDidEndEditing:) is also clearly
defined in the documentation:
"The NSEditorRegistration informal protocol is implemented by
controllers to provide an interface for a view, the editor, to inform
the controller when it has uncommitted changes."
