Description

The following code used to work in Wicket 8 and before and refresh the entire page:

@Override
protected void onSaved(IPartialPageRequestHandler target) {
    target.add(findPage());
}

In wicket 9 it gives:

java.lang.IllegalArgumentException: cannot update component that does not have setOutputMarkupId property set to true. Component: [Page class = nl.topicus.keyhub.web.pages.AccountProfielPage, id = 4, render count = 2]
	at deployment.keyhub-web-console.war//org.apache.wicket.core.request.handler.AbstractPartialPageRequestHandler.add(AbstractPartialPageRequestHandler.java:71)
	at deployment.keyhub-web-console.war//nl.topicus.keyhub.web.components.panel.AccountOverviewPanel$Config2FALink$1.onSaved(AccountOverviewPanel.java:61)

	at deployment.keyhub-web-console.war//nl.topicus.keyhub.web.components.form.UpgradingSubmitLink.onSubmit(UpgradingSubmitLink.java:37)

Calling setOutputMarkupId(true) on the page fixes the error, but IMHO does not make much sense.
