You may want to download an example from Apple ;-) :

Thanks for this link. It did help me a lot.
One problem though:
If I bind the content of my dictionary controller to "selectedObjects"
of my array controller, then I get an exeption: "Cannot create
NSDictionary from object () of class NSCFArray".
Makes sense: the content of the array controller is bound to some
instance variable which is initially nil.
The workaround (also used in samplecode/DictionaryController): observe
the array controller forKeyPath: @"selectionIndexes" and set some
instance variable (like currentlySelectedDictionary) from
"selectedObjects" whenever the selection changes.
Then bind the content of my dictionary controller to
"currentlySelectedDictionary".
Looks kind of clumsy, but works.
Is there some more elegant way?
Kind regards,
Gerriet.
