| <p>The Apache Wicket PMC is proud to announce Apache Wicket 8.0.0-M9!</p> |
| <p>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 https://wicket.apache.org</p> |
| <p>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.</p> |
| <h2 id="new-and-noteworthy">New and noteworthy</h2> |
| <p>Before <a href="https://issues.apache.org/jira/browse/WICKET-6498">WICKET-6498</a> users used to create a custom implementation of IHeaderResponseDecorator to place JavaScript items inside page body:</p> |
| <figure class="highlight"><pre><code class="language-java" data-lang="java"> <span class="nd">@Override</span> |
| <span class="kd">public</span> <span class="kt">void</span> <span class="nf">init</span><span class="o">()</span> |
| <span class="o">{</span> |
| <span class="n">setHeaderResponseDecorator</span><span class="o">(</span><span class="k">new</span> <span class="nc">JavaScriptToBodyCustomResponseDecorator</span><span class="o">(</span><span class="s">"footer-container"</span><span class="o">));</span> |
| <span class="o">}</span></code></pre></figure> |
| <p>See <a href="https://ci.apache.org/projects/wicket/guide/7.x/single.html#_put_javascript_inside_page_body">user guide</a> 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:</p> |
| <figure class="highlight"><pre><code class="language-java" data-lang="java"> <span class="nd">@Override</span> |
| <span class="kd">public</span> <span class="kt">void</span> <span class="nf">init</span><span class="o">()</span> |
| <span class="o">{</span> |
| <span class="n">setHeaderResponseDecorator</span><span class="o">(</span><span class="n">response</span> <span class="o">-></span> |
| <span class="o">{</span> |
| <span class="k">return</span> <span class="k">new</span> <span class="nf">ResourceAggregator</span><span class="o">(</span><span class="k">new</span> <span class="nc">JavaScriptFilteredIntoFooterHeaderResponse</span><span class="o">(</span><span class="n">response</span><span class="o">,</span> <span class="s">"footer-container"</span><span class="o">));</span> |
| <span class="o">});</span> |
| <span class="o">}</span></code></pre></figure> |
| <h2 id="caveats">Caveats</h2> |
| <p><a href="https://issues.apache.org/jira/browse/WICKET-6498">WICKET-6498</a> 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.</p> |
| <h2 id="using-this-release">Using this release</h2> |
| <p>With Apache Maven update your dependency to (and don’t forget to |
| update any other dependencies on Wicket projects to the same version):</p> |
| <figure class="highlight"><pre><code class="language-xml" data-lang="xml"><span class="nt"><dependency></span> |
| <span class="nt"><groupId></span>org.apache.wicket<span class="nt"></groupId></span> |
| <span class="nt"><artifactId></span>wicket-core<span class="nt"></artifactId></span> |
| <span class="nt"><version></span>8.0.0-M9<span class="nt"></version></span> |
| <span class="nt"></dependency></span></code></pre></figure> |
| <p>Or download and build the distribution yourself, or use our |
| convenience binary package</p> |
