NSObjectController can't observe NSArrayController's selection?

Subject: NSObjectController can't observe NSArrayController's selection?

I have an NSArrayController's contentArray bound to an array of dictionaries, all of which have a 'name' key.

Now I can bind a text field to the array controller, key 'selection' and path to 'name', and it will show the 'name' property of the selected dictionary.

But if I add an NSObjectController, bind it to the array controller, key set to 'selection' and no path, expecting it to now reflect the selected dictionary. Then I bind a text field to the object controller, key 'selection' and path 'name', but nothing happens.

Shouldn't this work? What am I missing?

Gerd
