when i try to use addrenderheaderlistener in application with header
contributor using methods other than renderonloadjavascript and
renderOnDomReadyJavascript,i get the exception as ajaxrequesttarget expects
"Only methods that can be called on IHeaderResponse outside renderHead() are

attaching a quickstart that shows the behavior where ajaxselfupdatingtimer is
used.
exception as follows :-
Only methods that can be called on IHeaderResponse outside renderHead() are
renderOnLoadJavascript and renderOnDomReadyJavascript
