The code is supposed to copy over the layout but css-layout.xml is missing. Also “css” should not be part of the name anymore.
Currently it fails with this:
org.apache.wicket.WicketRuntimeException: Method onRequest of interface org.apache.wicket.behavior.IBehaviorListener targeted at org.apache.wicket.ajax.markup.html.form.AjaxSubmitLink$1@anonymised.com on component [AjaxSubmitLink [Component id = link]] threw an exception
