The 'NewsItemReference'  class is defined in SilvaNews.adapters.newsprivoder.  
It looks like a simple wrapper around a news item.  It does not provide a 
helper method to get the actual item.  You could easily add one
(def get_wrapped_item(self): return self._item)

Or, you'll need to use an ExternalMethod that, given a NewsItemReference item, 
returns item._item.

I might file a bug for this, as you should be able to get the wrapped item 
within protected code.

Cheers,
Andy
