title: ngFor not displaying array data
body: <p>I have a component that is being passed in a number of objects through an input.</p>
  
  <pre><code>&lt;rooms-component [rooms]="Rooms$ | async"&gt;&lt;/rooms-component&gt;
  </code></pre>
  
  <p>In the child component, I am putting all the objects inside an array in OnChanges</p>
  
  <pre><code>ngOnChanges() {
          this.rmArray= Array(this.rooms);
      }
  </code></pre>
  
  <p>And in the HTML I have a ngFor to display the data</p>
  
  <pre><code>    &lt;li *ngFor="let room of rmArray"&gt;
          {{ room.name }}
      &lt;/li&gt;
  </code></pre>
  
  <p>This does not display anything. I suspect it has something to do with how I am creating the array. Any help is appreciated. Thanks.</p>
