ngClass combine two expression types
<p>Using ngClass I am trying to combine two expression types such that they are data bound and updated with changedetection like this</p>

<pre><code>&lt;div [ngClass]="[test.value | myClassPipe, {'anotherClass': test.isValid}]"&gt;&lt;/div&gt;
</code></pre>

<p>Is the syntax wrong or is this not possible?</p>
