The approach your describing below will throw exceptions for checkboxes: WicketMessage: unable to set object null, model: Model:classname=[wicket.model.PropertyModel]:attached=true:[EMAIL PROTECTED]:expression=[searchInHistoricNames]:propertyType=[null], called with component [MarkupContainer [Component id = formelement, page = nl.amsterdam.rbrb.web.search.SearchPage, path = 2:maincontent:searchform:form:formElements:2:inputfragment:formelement.CheckBox, isVisible = true, isVersioned = false]] Root cause: wicket.util.convert.ConversionException: Can't convert null value to a primitive class: boolean for setting it on [EMAIL PROTECTED] at wicket.util.lang.PropertyResolver$MethodGetAndSet.setValue(Ljava.lang.Object;Ljava.lang.Object;Lwicket.util.convert.IConverter;)V(PropertyResolver.java:838) at wicket.util.lang.PropertyResolver$ObjectAndGetSetter.setValue(Ljava.lang.Object;Lwicket.util.convert.IConverter;)V(PropertyResolver.java:447) at wicket.util.lang.PropertyResolver.setValue(Ljava.lang.String;Ljava.lang.Object;Ljava.lang.Object;Lwicket.util.convert.IConverter;)V(PropertyResolver.java:136) at wicket.model.AbstractPropertyModel.onSetObject(Lwicket.Component;Ljava.lang.Object;)V(AbstractPropertyModel.java:182) at wicket.model.AbstractDetachableModel.setObject(Lwicket.Component;Ljava.lang.Object;)V(AbstractDetachableModel.java:131) at wicket.Component.setModelObject(Ljava.lang.Object;)Lwicket.Component;(Component.java:2042) at wicket.markup.html.form.FormComponent.updateModel()V(FormComponent.java:840) at nl.amsterdam.rbrb.web.form.FormPanel$5.component(Lwicket.Component;)Ljava.lang.Object;(FormPanel.java:214) <--- the line with formComponent.updateModel(); Regards, Erik.
