Re: Correct way to get current page instance

Hi,

Both are correct but the second way is the simpler one.
PageRequestHandlerTracker's purpose is to give you the instance for the
requested page (#getFirstHandler()) and the last/response page.
E.g. if you are at PageA and you click a link that does
setResponsePage(PageB) then first=PageA and last=PageB.

Correct way to get current page instance

2016-02-10 Thread Rakesh A 
Hi,
I see two possibilities to access current page instance using
"PageRequestHandlerTracker"
One

IRequestHandler requestHandler =
RequestCycle.get().getActiveRequestHandler();
if (requestHandler instanceof IRequestHandlerDelegate)
{
  requestHandler = ((IRequestHandlerDelegate)
requestHandler).getDelegateHandler();
}

if (requestHandler instanceof IPageRequestHandler)
{
  IPageRequestHandler pageRequestHandler = (IPageRequestHandler)
requestHandler;
  if (pageRequestHandler.isPageInstanceCreated())
  {
IRequestablePage page = pageRequestHandler.getPage();
  }
}

Two
   PageRequestHandlerTracker.getLastHandler(RequestCycle.get()).getPage();

Option#2 looks simpler, but
Is there any difference between the two?
What is correct way to get current page instance?

Regards,
Rakesh.A
