I think you need an atom or a ref: (def my-map (ref {:checkbox-state false})) (defn get-checkbox-state [] (@my-map :checkbox-state)) (defn set-checkbox-state [state] (dosync (commute my-map assoc :checkbox-state state))) Christophe --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
