title: How do I set value of DateTextBox?
body: <p>So basically I have these two DateTextBoxes and I want to copy the value from one to another? Sounds easy, right? Still, it is not...
  I tried to do it this way:</p>
  
  <pre><code>dojo.byId("datetextbox1").value = dojo.byId("datetextbox2").value;
  </code></pre>
  
  <p>it actually looks like the value changes as the content of the field changes, but it doesn't really. When I inspect the element with firefox it still contains the old value in the code and when I try to submit the form, the old value is sent!
  So my question is: how should I change that damn value?</p>
