Use of @Default.PageExists function with a page that contains a parameter
Hi - I need to check if a page is on the clipboard before calling it. (if its not already there it can't be called for the process I am running) The issue is the page requires a parameter. If I check without the parameter the page is not found. Is it possible to use the PageExist function with a parameter passed for the page?
@Default.PageExists("D_CheckList") -> This does not work - page is not found because it exists on clipboard as D_CheckList[F]
@Default.PageExists("D_CheckList['F']") -> This does not work
FYI: Properties on page are referenced like this: D_CheckList["F"].ID

Hi,
From the "D_" prefix on your page name, I can see the page you are looking to find is a data page. In most scenarios, by design, a data page will load as soon as its referenced if it does not already exist. You can, however, use findDataPageWithoutLoading, to confirm if it exists without loading it. A sample approach for this (in a java step):
PRThread currentThread = tools.getThread();
ClipboardPage theDataPage = ((com.pega.pegarules.priv.context.PegaThread)currentThread).findDataPageWithoutLoading("D_TestDataPage");
if(theDataPage!=null)
{
//add code for if exists
}
else
{
//add code for if it does not
}
Hope this helps!
