Januari 25, 2006 - Wicket 1.1.1 Available

After a couple of months without any significant problem the Wicket team has made available the first maintenance release of Wicket 1.1. This release features a backport of a Wicket 1.2 feature: the <wicket:message> tag, which enables you to create internationalized pages without having to resort to adding Label components with StringResourceModel for internationalizing the texts on a page. See the WicketMessageResolver JavaDoc for more information.

Further enhancements include:

  • Added check and better exception when servlet's init param is missing
  • Added label tags for generated input tags in CheckBoxMultipleChoice and RadioChoice
  • Fixed autolink NPE problem
  • Fixed bug in button that caused the value attirbute to disappear after form submit

Together with this release, the Wicket extensions project receives a maintance release.

This release is available through the download pages on SourceForge.

October 30, 2005 - Wicket 1.1 Available

The Wicket team is proud to announce the availability of Wicket 1.1 for download! Wicket is a Java component oriented web application framework that takes simplicity, separation of concerns and easy of use to a whole new level. Wicket web applications consist of HTML markup and Java classes. No strange languages, no strange markup, no configuration files , no specialized, expensive tools: just Java, HTML and you.

This Wicket version contains a lot of improvements from the 1.0 version. New features include:

  • Simplified feedback and validation - enables custom feedback strategies

  • JavaScript and CSS support for components - contribute JavaScript and CSS from your component to the using page
  • Markup Inheritance - enables template pages and components
  • Inclusion of external markup
  • Simplified Choice component - creating drop down, radio and list components was never this easy
  • Less dependencies - we removed several library dependencies
  • Customizable Form handling - easy for quick forms, easily enables full custom form processing
  • Improved resource handling
  • Date picker component - will not get you dates, but a JavaScript and text field enabled localized calendar component.
  • Improved URL handling
  • AJAX request handling support - support for two leading AJAX JavaScript libraries is available as separate downloads from our Wicket Stuff project: scriptaculous and DOJO toolkit

The Wicket team wishes to extend their gratitude to the user and developer community for their testing efforts and help, making this release a reality!

August 30, 2005 - Wicket 1.1-beta 4 Available

Wicket 1.1-beta 4 is available for download and testing. This is a beta release, so you may expect some API changes. We are busy in the end game before we freeze the API, and running behind on our published schedule for 1.1 final. In order to be able to ship 1.1 final soon, we need your testing support! Most notable features in this release are:

  • Removed the (optional) dependency on commons-fileupload, made the support internal for Wicket
  • Made the coupling of Wicket to the servlet spec more loose, enabling usage of Wicket on platforms outside a servlet container, such as portlets, or embedded servers

  • Invisible components are not rendered any more
  • Added basic AJAX support: DOJO and libraries are now available for experimentation.

See the complete list of changes here.

Please download this release and give us feedback.

August 22, 2005 - Maintenance release Wicket 1.0.2 Available

The Wicket development team has released the second maintenance release of the Wicket 1.0 branch. This release fixes some bugs, and with that introduces one API breaking change:

The API change involves the IResourceStreamLocator interface, where the locate method now takes a ClassLoader as an extra parameter. Passing in null will use the context classloader.

July 24, 2005 - Wicket 1.1-beta 1 Avaliable

Wicket 1.1-beta 1 is available for download and testing. This is a beta release, which means that API's might change. Most notable features in this release are:

  • JavaScript support - components can now contribute their own JavaScript to a page, opening up possibilities for very rich Wicket components.
  • CSS support - alongside with the JavaScript support, Wicket allows components to contribute their CSS to a page
  • Markup inheritence - Wicket pages were already able to inherit on the Java side, but now it is possible to 'constrain' the markup of sub pages to a certain place in the markup. If you thought that borders were difficult, this will make your life very easy!
  • Date picker - as a demonstrator for what you can do with our new JavaScript support, we have included a Date picker component in the wicket extensions package.
  • Component reference examples - an ongoing concern: documentation and component reference. We have started building small component examples in the Wicket examples project.
Please download this release and give us feedback on how you like these new features. A final 1.1 release will be available around begin september, so we need your feedback!

July 17, 2005 - NetBeans kickstart guide available

July 17, 2005 - Maintenance release Wicket 1.0.1 available

The Wicket development team has released the first (and probably last) maintenance release of Wicket 1.0. This release fixes some bugs and adds some missing functionality:

  • Only validate components that are visible
  • FeedbackPanel: made some methods that were not meant for overriding final, and added methods that make extending feedbackpanel easier
  • fixed bug in AbstractPropertyModel which gave problems using custom converters (overriding getConverter for a component) with compound property models

June 7, 2005 - Wicket 1.0 available for download

The Wicket development team has made the 1.0 final release available for immediate download. This release marks a huge milestone in the development cycle of Wicket. Go to the downloads page to download Wicket 1.0!

May 28, 2005 - Wicket on JavaOne 2005 / San Francisco

Come see Wicket on JavaOne this summer. Wicket is featured in two events:

We look forward to see you at JavaOne!

May 21, 2005 - 1.0 RC3 is out!

Finally, after a month of some silence, we have produced our last release candidate before we deploy 1.0. If all goes well, you will see the final release within a week or two. The bug list now only contains an issue relating to clustering. As such we advise you currently to not deploy your application on a cluster, until the issues are resolved, or to be very thorough in your clustering tests.

In this release you won't see major API changes, however the internals have improved significantly. The request cycle has now correct semantics, we have improved the redirect after post pattern, which now performs significantly better than before, and allows you to do your request handling and rendering in one pass, and then redirect to the rendered page. CompoundModel support has improved and works with more components than before. We added support for redirecting to external url's (e.g. Google) directly by introducing RedirectPage.

For the complete list of fixes, updates and changes please see the release history.

May 4, 2005 - Eclipse Live Demo available

Using Wink we have put together a live Eclipse Demo showing how to get started developing your first Wicket application.

April 22, 2005 - Last Call for Wicket 1.0!

Wicket needs your input!

The Wicket team is preparing the final Wicket 1.0 release candidate. Therefore we need your help. If you have things that are hard for you to accomplish using Wicket, if there is something you posted to the mailinglist and it didn't get resolved, if you have a killer idea that absolutely must be in 1.0 or else...

Send it to the mailinglist or create a bug report!

The Wicket team want the RC3 to be the final release for Wicket 1.0. After this, development will focus on creating 1.1 with full support for AJAX, JavaScript, CSS and more.

This is the final call for changes to Wicket 1.0.

With regards,

The Wicket Team

April 16, 2005 - 1.0 RC2 is out!

We are getting close to a final 1.0 release in the near future. This RC2 release marks the next milestone on the journey to the first production ready release of Wicket. Many of the problems found by RC1 users have been solved and this release should be a much smoother ride for all.

See the changes report for more information on the solved bugs in this release.

April 3, 2005 - 1.0 RC1 is released!

The Wicket team is proud to release the first 1.0 release candidate. This is probably the most important milestone in our history. From now on the feature list has been frozen, and the bug list will shrink. Please take a look at the changelog for this release.

A list of the most note worthy changes:

  • Addition of Wicket namespace for identifying components: instead of id="wcn:foo" we now use wicket:id="foo" .
  • Support for clustering
  • CompoundPropertyModel makes development of forms much easier and less verbose
  • Added factories for creating your own Session, RequestCycle, etc. objects. Many things are configurable in Wicket using factories.
  • Moved non-core stuff to the Wicket Stuff project.

April 3, 2005 - Live Examples

Juergen Donnerstag has created a live examples website for everyone to see what can be done with Wicket without having to deploy the examples yourself!

March 19, 2005 - A new Wicket project is born: Wicket Stuff

We have registered a seperate project for hosting non-core components: Wicket Stuff . If your component has a dependency other than the Wicket dependencies , for example a Hibernate component, then Wicket Stuff is the place to find it.

The initial list of components hosted there is:

  • Velocity Panel
  • Hibernate components and helpers
  • Groovy integration
  • Spring Framework integration
  • fValidate integration

Releases of these projects will come available as Wicket 1.0 RC1 ships.

March, 4, 2005 - 0.9.19-beta released

The releases are getting smaller, so it is nearly that special time for RC1. The current release marks the work done between 0.9.18-beta and now. An issue regarding dependencies of Wicket has been resolved. Wicket doesn't depend any more on difficult to distribute libraries.

Februari 20, 2005 - 0.9.18-beta released

The Wicket team has worked really hard to make this beta release possible. The march to the big 1.0 is on, and the first release candidate will surface in the next few weeks.

A lot has changed in this release, so you will receive some compile time errors if you are coming from a previous release. Among the changes are the following:

  • Added a FAQ section to our site
  • Renamed handleX() methods and other events to conform to the onX() pattern.
  • Added Button class and Form buttons support. When it has two or more buttons, the onSubmit() handler is called on the button which submitted the Form.
  • Changed HtmlPage to WebPage, HtmlContainer to WebContainer and HtmlComponent to WebComponent
  • Reorganized components and examples for final 1.0 structure.
Check out all modifications on our release history page.

January 25, 2005 - 0.9.17-beta released
