title: Why can't I use two date picker components on a dialog?
body: <p>Here is an example xpage:</p>
  
  <p>I am trying to put multiple date pickers on a dialog box from the extension library, i get this error...</p>
  
  <p>Problem submitting area of page when I open the dialog...
     Tried to register widget with id==_Container but that id is already registered</p>
  
  <p>I'm not sure why it can't be done, anyone had any luck with it.</p>
  
  <p>Thanks</p>
