- * Managed form wraps a form widget and adds life cycle methods for form parts.
- * A form part is a portion of the form that participates in form life cycle
- * events.
- * <p>
- * There is requirement for 1/1 mapping between widgets and form parts. A widget
- * like Section can be a part by itself, but a number of widgets can join around
- * one form part.
- * <p>
- * Note to developers: this class is left public to allow its use beyond the
- * original intention (inside a multi-page editor's page). You should limit the
- * use of this class to make new instances inside a form container (wizard page,
- * dialog etc.). Clients that need access to the class should not do it
- * directly. Instead, they should do it through IManagedForm interface as much
- * as possible.
