title: Polymer 1.0 Global Variables
body: <p>In Polymer 0.5 the advice on globals was as outlined in this question/answer:</p>
  
  <p><a href="https://stackoverflow.com/questions/24867741/polymer-global-variables/24876397#24876397">Polymer global variables</a></p>
  
  <p>However in Polymer 1.0 this doesn't seem to work. Change notifications are not automatically generated on the underlying model, they are generated on the <code>&lt;dom-module&gt;</code> instead which means that change notifications will be generated on only one of the <code>&lt;app-globals&gt;</code>. </p>
  
  <p>What is the recommended way of implementing this pattern in Polymer 1.0?</p>
