title: Google App Maker - Problems setting UI visibility by role
body: <p>I am trying to set a widget's visibility based on <strong>one of many roles</strong>. The log seems to return the proper values, but the ui doesn't respond properly.</p>
  
  <p><strong>Logger is showing:</strong><br>
  User Role: Admins<br>
  Server returns: true</p>
  
  <p><strong>Client Script:</strong> ('visible' property)</p>
  
  <pre><code>google.script.run.withSuccessHandler(function(visible) {
    console.log("Server returns: " + visible);
  }).vis_canUnwind(@user.roles)
  </code></pre>
  
  <p><strong>Server Script:</strong></p>
  
  <pre><code>function vis_canUnwind(role){
  console.log("User Role: " + role);
    if(role == "Admins"||"DeptHeads"){
        return true;
      }else{
        return false;
     }
  }
  </code></pre>
  
  <p>If I use <strong>(@user.roles).indexOf('Admins') > -1</strong> <em>(as the visible property)</em> then it works properly so I'm sure it's related to my code.</p>
