I have seen a few posts about this problem, but nobody seems to have an answer.
When using an a4j:outputPanel to reRender a t:inputCalendar the page blows up and all you see is the calendar icon in the upper left corner and nothing else. I have seen some posts that say it is because the t:inputCalendar uses document.write instead of DOM manipulation, and others that say it is because there is something in the header that tomahawk needs that a4j doesn't include. Regardless, nobody seems to have an answer why you can't reRender a t:inputCalendar inside of an <a4j:outputPanel>
Any and all help is greatly appreciated.
if page blows up it points to the document.write usage. So, you have no chance to use it in re-rendered area.
