Dear Wicket Boffins,
I have a Wicket 6 app that I’ve recently migrated to Wicket 7. In the app
there is a form whose AjaxSubmitLink hides the form as part of the submit. In
Wicket7, this causes a ListenerInvocationNotAllowedException to be thrown,
since the component that submitted the form is no longer visible. What is the
approved “wicket way” to do what I’m attempting?
Thanks in advance.

Here’s a stripped down version of the code:
JAVA:
public class TestPage extends WebPage {
public TestPage() {
Form form = new Form("form");
form.add(new AjaxSubmitLink("submit") {
@Override
protected void onSubmit(AjaxRequestTarget target, Form<?> form) {
super.onSubmit(target, form);
form.setVisible(false);
target.add(form);
}
});
add(form.setOutputMarkupPlaceholderTag(true));
}
}
HTML:
<html xmlns="http://www.w3.org/1999/xhtml";
xmlns:wicket="http://wicket.apache.org";>
<body>
<h3>Test Form Submit Hides Form</h3>
<form wicket:id="form">
<h4>Form Element</h4>
<input type="submit" wicket:id="submit" value="Submit"/>
</form>
</body>
EXCEPTION THROWN ON SUBMIT:
org.apache.wicket.core.request.handler.ListenerInvocationNotAllowedException:
