Hello everybody
Bindings problem:
I have an NSArrayController subclass and an NSPopUpButton subclass.
I am trying to bind the NSPopUpButton's selected object to the
selection of my array controller.
I have to do this manually for reasons I won't get into here.
But when I do this (self is myPopUpButton)
[self bind:@"selectedObject" toObject:ArrayController
withKeyPath:@"selection" options:nil];
I get the error that my array controller is not KVC for the key path
selection.
"selection" is definitely a controller key option in Interface
Builder, is it possible that this doesn't work programmatically?
Has anyone else run into this problem???
I want to bind to the selected object, not the index... so it seems
my only option here is selectedObjects, which I will have to pass an
array of one object to.
Even if you didn't get the error, this approach wouldn't work. The
selectedObject must be an exact object from the content collection. -
selection returns a proxy object. You might try barking up using
selectedValue instead. But then, you might still have the binding
error, or it might go away since you are binding through selection.
Anyway, have you verified that the ArrayController variable is what
you expect it to be at the point that bind: is called?
