import mx.controls.Alert;
import flash.accessibility.Accessibility;

mx.accessibility.AlertAccImpl.enableAccessibility();

var sessionTimeout;
var sessionNotificationTimeout;
var timeLimit: Number = 60000;
var sessionAlert: Alert;
resetTimeout();

testField.addEventListener("change", resetTimeout);

function resetTimeout() {
  clearTimeout(sessionTimeout);
  clearTimeout(sessionNotificationTimeout);
  sessionTimeout = setTimeout(endSession, timeLimit);
  sessionNotificationTimeout = setTimeout(showTimeoutAlert, timeLimit - 20000);
}

function showTimeoutAlert() {
  sessionAlert = Alert.show("Click the YES button to extend your session",
  "Your login session is about to expire, do you need more time?",
  Alert.YES | Alert.NO, null, handleAlertClick);
}

function endSession() {
  sessionAlert.deletePopUp();
  Alert.show("please log in again",
  "Your session has expired");
}

function handleAlertClick(e) {
  if (e && e.detail && e.detail == Alert.YES)
  resetTimeout();
