When a widget's value is None and the form is not being redisplayed (after validation fails) then the default value for the widget becomes it's value. In SelectionField.update_params _is_option_selected (http://tinyurl.com/ya8slk) is called to see which option is being selected so it can add the "selected" attribute to to the selected option tag.
