component this is a very powerful component but with some limitations that must be understood before using it ajaxformloop allows in a limited way dynamic addition of 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 bean a new row is added to the loop with the given set of components and these components if form fields are bound to the newly instantiated bean continue reading share this share on facebook opens in new window facebook share

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 you want to create a wizard just keep on using the same method inside the dialog box there is also a modalbox hide method to hide the dialog continue reading share this share on facebook opens in new window

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 rather than assisting supervise and most action based frameworks leave even the integration to the developer tapestry provides you with events which you can easily connect to your javascript events
