title: angular 4: *ngIf with multiple conditions
body: <p>I'm confused a bit. I need to hide block if result have one of several cases. But seems it not working correctly...</p>
  
  <pre><code>&lt;div *ngIf="currentStatus !== 'open' || currentStatus !== 'reopen' "&gt;
  
      &lt;p padding text-center class="text-notification"&gt;{{message}}&lt;/p&gt;
  
  &lt;/div&gt;
  </code></pre>
  
  <p>It's just appeared with other condition. It doesn't work neither 1 condition nor for 2. Also tried <code>*ngIf="currentStatus !== ('open' ||  'reopen') "</code> but it's works ok only for 1 case. </p>
