> I have a query string that I need to append to a  Link object, the query string is:
> ?gender=M&country=
>  Link lnk = renderLinkSource.createPageRenderLink("SamplePage");
>  lnk.addParameter("gender", "M");		// this works
>  
> lnk.addParameter("country", null);		
> above line failed with :
>  RequestExceptionHandler Unexpected runtime exception: Parameter value was null or contained only whitespace.
> A null parameter should be valid in a URL, sometimes it is needed to have Google Analytics pick up the complete URL even it is null.
