get-shared not working?

shared.cljs

(ns tag.main
  (:require
    [om.core :as om :include-macros true]
    [om.dom :as dom :include-macros true]))

(defn- header-component
  [state owner]
  (om/component
   (dom/section nil
    (dom/h1 nil "Hello!")
    (dom/p nil (str "queue? [" (str (om/get-shared owner :queue)) "]"))
    (dom/button #js {:onClick #(.log js/console (om/get-shared owner :queue))}
                            "Click!"))))

(defn- frame-component
  [state owner]
  (om/build header-component state))

(defn install-root-view!
  []
  (om/root frame-component (atom {}) {:target js/document.body
                                      :shared {:queue :queue}}))

(set! (.-onload js/window) install-root-view!)

This broke because I forgot to wrap "om/build" in (om/component (om/build ...)).
