TW doesn't (currently) merge recursively schemas' and compound
widget's validators. You'd have to place the ForEach insde the
CheckBox widget for it to work:
class ArticleForm):
validator = Schema(filter_extra_fields = True, allow_extra_fields =
True)
class fields(WidgetsList):
....
categories = CheckBoxList(validator=ForEach(...))
