Apache Tapestry - Architecture Advertisements. With the move to the new code base, upgrades have been minimally painful, and growing easier with each release. There's only so far you can go in an action oriented framework when you have the same behaviors spanning many different pages.

Apache Tapestry - Architecture
In fact, the exception is wrapped inside a ComponentEventExceptionfrom which you may extract the event type and context. T5 is build around great IoC container which should be promoted more by T5 team and thanks to that it is easy to reconfigure default behavior of service classes logic layer you build on top of html like templates how much tapestry tags are put into view depends just on your coding style It is easy to persist state xction server side when needed, however, by default it is just like you mentioned.
In general I always though Java webapps are most i to develop, maintain and host. The URL doesn't say what happens when the link is clicked, it identifies which component is responsible when the link is yapestry5.
Alternatively, we can use the EventLink component, in which case the name of the event is determined by us — either through the "event" parameter or the element's ID:. I have used both to do a 'glorified hello world' type of applications and i feel like both are very similar.
The only head to head I've seen performance wise gave play a small advantage against Tapestry 5.

Lewis Ship Apr 1 '11 at As an alternative to the use of annotations, you may name your event handling methods following a certain convention, and Tapestry will find and invoke your methods just as if they were annotated. Using OnEvent on a method and not specifying a specific component ID means that the method will be tpestry5 for events tapstry5 any component.
Xction provides a new dimension to the web application and the programming is quite Simple, Flexible, Understandable and Robust. Why would one choose one over the other. For the typical case an exception thrown by an "activate" or "action" eventthis will be a navigational response such as a page instance or page name.
In the above example, the editDocument method will be invoked when any event occurs in in the "edit" component and has at least one context value.
This filter checks the java classes for changes and update the application as necessary. Both are stateless frameworks i know play is more stateless Both really boost developer productivity with live class reloading Why would one choose one over the other.
When a sub-class overrides an event handler method of a base class, the event handler method is only invoked once, along with any other base class methods. But a colleague in a project where we use Play has worked with it, and he was really fed up with it. However, only a simple conversion to string occurs. To support testing, it's a common practice to give event handler methods package-private visibility, as in the examples on this page, although technically they may have any visibility even private.
There is also good and helpfull modules on Tapestry. For example, a form component may trigger an action event, which will then trigger notification events to announce when the form submission is about to be processed, and whether it was successful or not, and those event could be further handled by the page component.
A containing component can then respond to it, if desired, with an "onUpdateAll " method in its own component class. For the OnEvent annotation, the value attribute identifies the name of the event to match. It's a bit like Maven acton know, there is A way to do it well, but it's not always clear.

For some components, more than one type of event can occur, in which case you will want to be more specific:. BTW tapestry 5 in action book just became available on MEAP Once again, please note that I have no idea axtion play and was only trying to address points you mentioned.
Component events are Tapestry's way of conveying a user's interactions with the web page, such as clicking links and submitting forms, to designated methods in your page and component classes. On every Tapestry upgrade, you need tapesry5 change your code as methods are deprecated - not only in your own code but all other modules from 3rd parties you have integrated.
