title: GWT Clone a widget using DOM.clone
body: <p>I wish to programatically clone a widget.  I am able to clone the Element inside the Widget with Dom.clone but I don't seem to be able to create a Widget from this cloned element.  Is this possible?</p>
  
  <pre><code>        //somewhere in onModuleLoad()...        
      Button button = new Button("Original"); 
      RootPanel.get().add(button);
  
      //.....later on...
      Element buttonCloneElement = DOM.clone(button.getElement(), true);
      Widget buttonClone;
  
      buttonClone = new Button(buttonCloneElement);  //FAIL - No such constructor
      buttonClone.setElement(buttonCloneElement);    //FAIL - No such setter method
  
      //This may work but looks messy to me
      buttonClone.getElement().setInnerHTML(button.getElement().getInnerHTML()); 
  
      //add the clone to the root panel??
      RootPanel.get().add(buttonClone);
  </code></pre>
  
  <p>Is there another way of cloning the Widget? </p>
