Demonstration of page flow design patterns.
#if ($courseBooking) Course Booking CompletedBooking No. | $courseBooking.id |
Booking Created | $format.date($courseBooking.createdAt, "dd MMM yyyy - h:mm:ss a") |
Customer Name | $customer.name |
Customer No. | $customer.id |
Course Date | $format.date($courseBooking.bookingDate, "dd MMM yyyy") |
Course Type | $courseBooking.courseType |
The LastPage gets the booking details from a "bookingId" URL request parameter.
String bookingId = getContext().getRequest().getParameter("bookingId="); CourseBooking courseBooking = getBookingService().findCourseBookingByID(new Integer(bookingId));The advantage of the Post-Redirect pattern is that it will not make the POST request again of the previous page even if the users does a refresh. To prevent users from submitting the order twice by pressing the back button, the StartPage of this page flow uses a form submit check.
public class StartPage extends BorderedPage { .. public boolean onSecurityCheck() { return form.onSubmitCheck(this, "/invalid-submit.html"); } }
