Created February 17, 2015 08:25

Demonstrating how ref-cursors + state can combine to cause double-renders

	(ns om.repro.state-and-ref-cursors
	(:require [om.core :as om :include-macros true]
	[om.dom :as dom :include-macros true]))

	(defonce app-state (atom {:foo {}}))

Demonstration that Om cursors can quietly dereference to someone else's path. If you quickly move your mouse over this list of names, the assert fails, because you switch up the app-state indices and then cause another event before a render updates the paths.

	(ns explore-om.stalecursors
	(:require-macros [cljs.core.async.macros :refer [go-loop]])
	(:require [om.core :as om :include-macros true]
	[om.dom :as dom :include-macros true]
	[cljs.core.async :refer [put! chan <!]]))
