      • handleRequest

        public boolean handleRequest​(RequestKeys keys)
                      throws WebException
        This is the main method. It handles the events in the request.
        First it calls the getEventsFromRequest method to get an ordered list of the events that needs to be handled, then it process each one of the events. The process of each event consists on:
        1. creating the target page of the event (with the createPage method)
        2. processing the page (with the processPage method).
        At the end it checks if the page needs to be tracked and if so calls the saveReturnToPage method, which combined with the ReturnTo event supports to go back to the last visited page.
        Also, if the page is in succesful state, it calls saveLastSuccesfulPage, this combined with the fact that if at the end the page is in cancelled state the servlet calls restoreLastSuccesfulPage, provide support for cancelling beans execution.
