title: Angular2 - Textarea validation how to force blur
body: <p>My form is submitted via the <strong>Enter</strong> key. The value of the <strong>textarea</strong> is null, since the focus is still on the <strong>textarea</strong>.</p>
  
  <p>Is there a way to force blur on the <strong>textarea</strong>, or is there any more graceful approach?</p>
