Apache Wicket 8.0.0-M9 released

17 Feb 2018

The Apache Wicket PMC is proud to announce Apache Wicket 8.0.0-M9!

Apache Wicket is an open source Java component oriented web application framework that powers thousands of web applications and web sites for governments, stores, universities, cities, banks, email providers, and more. You can find more about Apache Wicket at http://www.tuomi77.top

This release marks another minor release of Wicket 8. We use semantic versioning for the development of Wicket, and as such no API breaks are present breaks are present in this release compared to 8.0.0.

New and noteworthy

Before WICKET-6498 users used to create a custom implementation of IHeaderResponseDecorator to place JavaScript items inside page body:

    @Override
    public void init()
    {
       setHeaderResponseDecorator(new JavaScriptToBodyCustomResponseDecorator("footer-container"));
    }

See user guide for more details. Now each application has a default IHeaderResponseDecorator, which decorates header responses with a ResourceAggregator. Applications have to make sure, that each response is now explicitly decorated with a ResourceAggregator too:

    @Override
    public void init()
    {
       setHeaderResponseDecorator(response -> 
       {
            return new ResourceAggregator(new JavaScriptFilteredIntoFooterHeaderResponse(response, "footer-container"));
       });
    }

Caveats

WICKET-6498 might not work as expected due to a known issue with all major browsers (Chrome, Firefox, IE > 10) which allows deferred scripts to be executed before DOMContentLoaded is fired. For this reason WICKET-6498 should be avoided for production applications and used carefully.

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>8.0.0-M9</version>
</dependency>

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

Upgrading from earlier versions

If you upgrade from 8.y.z this release is a drop in replacement. If you come from a version prior to 8.0.0, please read our Wicket 8 migration guide found at

Have fun!
