> "With great pleasure we announce the availability of Apache Wicket 6.0.0"
> -- Martijn Dashorst, Vice President, Apache Wicket
> Apache Wicket v6.0.0 is the 6th major release of the popular open
> source Java web framework. Numerous enhancements make Apache Wicket
> v6.0.0 a solid choice for web development:
> - Out-of-the box JQuery integration
> - Complete control over AJAX requests
> - Improved event registration in browsers
> - Support for large datasets in components
> - Dependency management for client side javascript libraries
> - Experimental support for websockets
> Additional features include a customizable client-side API, improved
> feedback messages, correct packaging for OSGi compatibility and
> improved initialization of plugins. Highlights include:
> Java 6 required -This release moves the minimum required Java version
> to Java 6. This means that Wicket applications running on earlier Java
> versions meaning to upgrade, also need to upgrade their Java runtime.
> Revamped Wicket AJAX now leverages JQuery - Wicket's custom AJAX
> JavaScript library has been re-implemented using JQuery. This makes it
> easier to integrate JQuery plugins into Wicket applications. With the
> new AJAX implementation it is possible to provide your own version of
> JQuery should the need arise, or even to replace the whole Wicket
> client side AJAX implementation.
> AJAX Attributes - With the new and improved AJAX implementation, you
> can alter any aspect of an AJAX request through AjaxRequestAttributes.
> For example you can specify that the request should be executed using
> POST instead of GET, or that the AJAX request should be multi-part,
> etc. See the migration guide or the JavaDoc of AjaxRequestAttributes
> for all possible options.
> Browser event registration replaces inline events - Wicket now uses
> JavaScript event registration instead of inline attributes for AJAX
> components. This enables multiple event listeners to be attached to a
> markup tag, cleans up the rendered markup considerably and reduces the
> amount of generated markup.
> IDataProvider now uses long instead of int - The IDataProvider<T>
> interface and implementations now use long instead of int for index
> and size parameters to better line up with the Java Persistence API
> and other persistency frameworks. Big data is now possible with
> Wicket!
> ${label} replaces ${input} in feedback messages - Previous Wicket
> versions used the input that was provided by users in error messages
> when validations failed. This led to error messages like "1234a is not
> a valid number". In Wicket 6 the feedback messages use the label of
> the invalid form component instead. You can set the label by calling
> setLabel() on the form component. If no label is provided, Wicket
> defaults to displaying the component identifier. This changes the
> error message to "Phonenumber is not a valid number".
> Resources can declare dependencies - It is now much easier to create
> resource contributions with dependencies, for example a JQuery plugin
> can declare a dependency on JQuery and other resources such as
> embedded style sheets. Users of such resources don’t have to provide
> these dependencies themselves, and the dependencies are linked in the
> appropriate order.
> Packaged resources will use minimized version automatically - When a
> minimized JavaScript resource is available (filename.min.js – add the
> .min part to the filename before the extension), Wicket will
> automatically use the minimized version when running in deployment
> mode, while using the non-minimized version for development mode.
> OSGi compatible packaging - Wicket's packaging has been made
> compatible with OSGi bundles by moving some classes to different
> packages. The full list can be found in our migration guide. This
> makes it much easier to deploy Wicket applications in an OSGi
> environment.
> Experimental websocket implementations - This release also includes
> two experimental websocket implementations: one using Atmosphere as a
> bridge for browsers and containers that don't support websockets
> natively and one for containers and browsers that have native
> websocket support.
