public class CustomBooleanEditor extends PropertyEditorSupport
This is not meant to be used as system PropertyEditor but rather as locale-specific Boolean editor within custom controller code, to parse UI-caused boolean strings into boolean properties of beans and check them in the UI form.
In web MVC code, this editor will typically be registered with
binder.registerCustomEditor
calls.
