title: Angular async pipe and object property
body: <p>I need to use async pipe without ngFor. I need to check property of object that is async loaded with observable. </p>
  
  <p>This is what i want, but not working:</p>
  
  <pre><code> &lt;ion-item *ngIf="user$.anonymouse | async"&gt;
       &lt;ion-label&gt;Login&lt;/ion-label&gt;
   &lt;/ion-item&gt;
  </code></pre>
  
  <p>//EDIT: I getting this error when i use code above</p>
  
  <blockquote>
    <p>EXCEPTION: Invalid argument 'true' for pipe 'AsyncPipe' in [!user$.anonymouse | async in SettingsPage@27:22]</p>
  </blockquote>
  
  <p>Is there any way how to solve this?</p>
  
  <p>I know i can subscribe to this observable in Ctrl a store values into normal variable but i dont want to do that, because of perfomance etc.</p>
