Hi CG, >can we listen to an event and act in ajax way Of course, it is not uncommon to return a JSON object from an event.
It is not exactly clear to me exactly what you are trying to do, and how your UI glues together but you should be able to do exactly what you require, read up a little on how to use eventlinks, zones (now also MultiZoneUpdate) and even event bubbling, after all Tapestry is event driven!

Peter, you have gave me some hints , I think I know which approach should I use then ... By the way , there is one more question , can we listen to an event and act in ajax way, meaning without refresh the whole page ? For example, when I click "New record" icon on the toolbar, the best is , we just clear all the field, and no need to call to reload the whole page. At the moment , I use the Zone to archive that , but the toolbar is not a component at the moment , I am not sure if I make the toolbar as an component , this trick still works or not ...
