Redux: Aktion bei Versand im Store nie gesehen.

Ich habe ein Nicht-React-Projekt mit dem folgenden Code
.

_index.js_

import configureStore from 'js/store/configureStore'

/* Redux Imports */
import { createPage } from 'js/actions/page'

// Boot the App
document.addEventListener('DOMContentLoaded', function () {
  const initialState = window.__INITIAL_STATE__
  const pageId = window.__INITIAL_STATE__.page
  const store = configureStore(initialState)
  store.dispatch(createPage(pageId))
})

*actions/page.js*
function initPage (pageId) {
  return {
    type: 'CREATE_PAGE',
    page: pageId
  }
}

export function createPage (pageId) {
  return dispatch => {
    dispatch(initPage(pageId))
  }
}

_reduzierer/page.js_

/**
 * Page Mediators get imported here
 * Page Mediators are brokers that hold page initialization.
 * The bundle includes all page mediators but they will not be activated
 * unless thre reducer calls them.
 */
import * as cart from 'js/templates/cart'

/**
 * This is a edge case, index.js boots the app and we are subscribing to 
 * a Redux @<strong i="11">@INIT</strong> action instead of adding one more layer of actions
 * which leads to unintended scenarios.
 */

const page = (state = {page: []} , action) => {

  console.log(state)
  switch (action.type) {
    case '@<strong i="12">@INIT</strong>':
      console.log('initializing page:' + state.id)
      console.log(state)
      dispatch({type: 'CREATE_PAGE',page: state.id})
      cart.init()
      return state
    case 'CREATE_PAGE':
      console.log('initializing page:' + state.id)
      cart.init()
      return state
    default:
      return state
  }
}
export default page

Das Problem, das ich habe, ist, dass actions/page.js die Aktion CREATE_PAGE nie sieht. Irgendwelche Gedanken?
