handle-change.cljs

;; Editing a class name and making it blank results in the following error:
;; Uncaught Error: No protocol method ITransact.-transact! defined for type string:  

; I changed:

(defn handle-change [e text owner]
  (om/transact! text (fn [_] (.. e -target -value))))

; to:

(defn handle-change [e text owner]
  (let [value (.. e -target -value)]
    (if (empty? value)
      (om/transact! text (fn [_] (js/String. "")))
      (om/transact! text (fn [_] value)))))
