Yes, correct. The model should be cleared as well.
And it indeed uses setDefaultFormProcessing(false).
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
