title: How do I make DateTextBox (dojo) still display invalid value date after submitting screen?
body: <p>I'm using DateTextBox from dojo library in my Web page.
  After entering an invalid value manually in DateTextbox then submitting the screen, this value disappears :(.
  My idea is to keep showing this value so that users can see which wrong value they have entered.
  How can I do this?</p>
  
  <p>Any help is highly appreciated,</p>
  
  <p>Thanks in advance :)</p>
