Practicing some KVO concepts.
I have this line
[person addObserver:textField forKeyPath:@"firstName"
options:NSKeyValueObservingOptionNew context:NULL];
person is App Controller's Person object.
textField is a NSTextField
person does have a "firstName" property of type NSString
When I click on a button that updates the firstName property I get this
message
2008-06-27 22:17:29.751 Bindings1[21896:10b] <NSTextField: 0x123c30>: An
-observeValueForKeyPath:ofObject:change:context: message was received but
not handled.
Key path: firstName
Observed object: firstName: Basic and lastName: Wait
Change: {
kind = 1;
new = Basic;
}
Context: 0x0
At least it's firing! ^_^
But I was sure since I have a firstName method and a setFirstName method it
would update the textField. I have used IB to bind the value of the
textField to the value of the person object and that works when I edit the
textfield (yay). So I know I have the proper methods. I think.
Am I doing something wrong? (I assume I am)

If you can't be kind, at least have the decency to be vague.
