Apache Wicket 6.6.0 released

The Apache Wicket PMC is proud to announce Apache Wicket 6.6.0!

This release marks the sixth minor release of Wicket 6. Starting with Wicket 6 we use semantic versioning for the future development of Wicket, and as such no API breaks are present in this release compared to 6.0.0.

New and noteworthy

wicket:for attribute for html label tags

While already available for some time, the wicket-1.5.xsd now contains a valid definition for the wicket:for attribute such that it

Can be used in HTML <label> element to automatically link it to a form element. The value of this attribute must have the same value of the form component’s wicket:id attribute.

So you can use the following markup:

<label wicket:for="someinput">Some label</label>
<input wicket:id="someinput" type="text">

Added a callback for an invalidated session

Session is extended with a life cycle event called onInvalidate(). This method is executed when the user session is invalidated either by explicit call to org.apache.wicket.Session#invalidate() or due to HttpSession expiration.

In case of session expiration this method is called in a non-worker thread, i.e. there are no thread locals exported for the Application, RequestCycle and Session. The Session is the current instance. The Application can be found by using Application#get(String). There is no way to get a reference to a RequestCycle.

Using this release

With Apache Maven update your dependency to (and don’t forget to update any other dependencies on Wicket projects to the same version):

<dependency>
    <groupId>org.apache.wicket</groupId>
    <artifactId>wicket-core</artifactId>
    <version>6.6.0</version>
</dependency>

Or download and build the distribution yourself, or use our convenience binary package

Upgrading from earlier versions

If you upgrade from 6.y.z this release is a drop in replacement. If you come from a version prior to 6.0.0, please read our Wicket 6 migration guide found at

Have fun!
