See this:

<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml";
  xmlns="*">
  <mx:Script>
    import mx.utils.ObjectCopy;
    function copyObject(source:Object):Object
    {
      var newObject:Object = ObjectCopy.copy(source);
      ObjectCopy.copyProperties(newObject, source);
      return newObject;
    }
  </mx:Script>
  <mx:Model id="model">
    <root>
      <item>
        <creature>elephant</creature>
        <legs>4</legs>
      </item>
      <item>
        <creature>human</creature>
        <legs>2</legs>
      </item>
    </root>
  </mx:Model>
  <mx:DataGrid id="grid" dataProvider="{copyObject(model.root).item}" />
  <mx:Button click="grid.removeItemAt(0)">
    <mx:label>grid.removeItemAt(0)</mx:label>
  </mx:Button>
  <mx:DataGrid id="grid2" dataProvider="{model.root.item}" />
</mx:Application>

copyObject() makes a copy of the object.  Clicking on the
"removeItemAt(0)" button removes the 1st item from the first grid
only.  So the original data provider object (which the second grid
uses directly) is not modified.
