Did you setup the bindings using Interface Builder or
programatically? If programatically, they work in only one
direction so you need to call
[object1 bind:@"value" toObject:object2
withKeyPath:@"whateverPathForKeyIs" options:nil]; and
[object2 bind:@"value" toObject:object1
withKeyPath:@"whateverPathForKeyIs" options:nil];
Otherwise, make sure you're content object is KVC/KVO compliant etc.
This isn't correct.
Setting bindings up manually vs IB is the same.
The message flow discussion in the Cocoa Bindings doc illustrates
how the data flows in both directions.
