title: How to use dijit/Textarea validation (Dojo 1.9)?
body: <p>I have textarea which is required field. I've found <a href="https://stackoverflow.com/questions/8072173/dojo-validation-of-a-textarea">post suggesting that Dojo doesn't have validation for Textarea</a>, but in Dojo 1.9, there's an argument 'required'. </p>
  
  <p>I've done the following:</p>
  
  <pre class="lang-javascript prettyprint-override"><code>new Textarea({required:true, value:""}, query('[name=description]')[0])
  </code></pre>
  
  <p>but the effect isn't what I've expected. The texarea has red border always, even if the field wasn't focused (as opposite to, for example, ValidationTextBox). But when I call:</p>
  
  <pre class="lang-javascript prettyprint-override"><code>form.validate()
  </code></pre>
  
  <p>the validation is passed even if the texarea is empty.</p>
  
  <p>Is it possible to get Textare behave the same as in ValidationTextBox, or as for now, the validation for that component is not yet ready and I'd have to write custom version (as in linked post) or wait for next Dojo?</p>
