Hi, Just trying this now, with current version of kitchen sink I got an error message starting the webapp, saying that no persistable classes could be found and to check value of isis.persistor.datanucleus.RegisterEntities.packagePrefix in isis.properties, but that key is in isis_datanucleus.properties.
Also errors in running fixture script :( - org.apache.wicket.WicketRuntimeException - Method onRequest of interface org.apache.wicket.behavior.IBehaviorListener targeted at org.apache.wicket.ajax.markup.html.AjaxLink$1@1ac79481 on component [AjaxLink [Component id = menuLink]] threw an exception -
