Can you move the call of setDefaultModel() to onConfigure() instead of
onBeforeRender() ?
It is not allowed to modify the models during rendering.

Summary: Using WicketMessageTagHandler on non-components prevents
Ajax behaviors
Key: WICKET-6843
URL: https://issues.apache.org/jira/browse/WICKET-6843
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 8.0.0
Reporter: Peter Franza
Inclusion of the wicket:message attribute on non-component markup prevents any
children that have ajax behaviors to not get bound in after render.
In the code below the markup will render correctly, however there will not be
any click event bound to the link. If the `wicket:message` tag is removed from
the div everything will work correctly. Additionally if the a `wicket:id` is
added to the div, and the div is treated as a component, then everything will
also work.
*Example code*
Source:
{code:java}
public class TestPage extends WebPage {
public TestPage(PageParameters p) {
super(p);
queue(new AjaxLink("link") {
@Override
public void onClick(AjaxRequestTarget target) {
target.appendJavaScript("alert('click');");
}
});
}
}

The fact that JDK 8 still has support (read gets bug and security fixes), does not mean that a framework like Wicket needs to put effort in supporting new features on this old JDK. Wicket 8 probably will be supported (read gets bug and security fixes) for several years to come. For new features, you will have to upgrade your entire stack not just Wicket. The Wicket team has limited resources and we cannot afford to spend it on supporting many different platforms. There is nothing stopping you from forking the Wicket source code and either backport the features you need from Wicket 9 to Wicket 8 or downgrade the Java version in Wicket 9 though. > CSP support in Java 8 > - > > Key: WICKET-6832 > URL: https://issues.apache.org/jira/browse/WICKET-6832 > Project: Wicket > Issue Type: New Feature > Components: wicket >Affects Versions: 9.0.0, 8.9.0 >Reporter: Ashley Reed >Priority: Major > > Wicket needs Content-Security-Policy support in Java 8 as it is it the most > popular version of Java used in production.
