sticky comments 4 this example is similar to securing tapestry pages with annotations part 1 my use case is to redirect a user to the starting page of a multiple step wizard in case a request is directly made to an intermediate step and the session has not been properly setup one way to solve this problem the ugly way is to add a condition to every entry point in the page public class mypage sessionstate create false private shoppingcart shoppingcart onevent eventconstants activate object activate if shoppingcart null return index class return null onevent eventconstants success object dosomething if shoppingcart null return index class the problem with this code is that you have to check this condition for all event handlers form eventlink etc a more elegant solution would be to use annotation secured by a componentrequestfilter continue reading share this share on facebook opens in new window facebook share on x opens in new window x email a link to a friend opens in new

components to a form these components are laid out inside the ajaxformloop each time the add new link is clicked addrow event is triggered this event requires the event handler to return a new value

see how difficult or easy it is to create one on our own we will use modalbox as it has an mit license and it is written in prototype soon this won t be a criteria for choosing a script as tapestry is going to be prototype independent the modalbox script is very easy to use there is a modalbox show method which displays a dialog box it takes a dom element and configuration options as parameters if

tapestry has an excellent support for javascript and ajax it strikes a perfect balance between how much a framework should assist and how much the developer should do most component based frameworks
