Description

After updating to the latest Tap 4.1.2, a PageNotFoundException is no longer
caught in the following piece of code in my border component.

public boolean isShowHelpLink() {
boolean show = true;
IPage currentPage = getPage();
String helpPageName = currentPage.getPageName() + "Help";
try

{ IRequestCycle requestCycle = getPage().getRequestCycle(); requestCycle.getPage(helpPageName); // Exception here is not caught }

catch (PageNotFoundException pnfe)

{ show = false; }

return show;
}

Instead, the exception is shown on the exception page :
org.apache.hivemind.ApplicationRuntimeException
There was an error borrowing the page with key PageKey[_pageName='HomeHelp' , _locale=en_GB ] from the page pool.

[ +/- ] Exception: Page 'HomeHelp' not found in application namespace.
org.apache.tapestry.PageNotFoundException
Page 'HomeHelp' not found in application namespace.
pageName: HomeHelp
