title: how to implement cascaded dialogs in DOJO Toolkit
body: <p>I was looking for cascaded (multi-level) dialogs in DOJO Toolkit. I understand that a proper implementation of this will be available in DOJO 1.4. (<a href="https://stackoverflow.com/questions/809350/dojo-dialog-nesting">Dojo dialog nesting</a>) </p>
  
  <p>I was wondering if a basic functionality of it (for managing the zIndexes) could be done easily by sub-classing the existing dijit.Dialog (1.3) class. If somebody can show a basic outline of how this can be done, it would be great.</p>
