DynaValidatorForm and Update Object

Hi, I am wondering if there is a possibility to use DynaValidatorForm
in the following method.
How is it possible to set a Bean into the bookEditForm (if that would
be a DynaValidatorForm) ?

    public ActionForward editBook(
            ActionMapping mapping,
            ActionForm form,
            HttpServletRequest request,
            HttpServletResponse response) {
            BookEditForm bookEditForm = (BookEditForm) form;

            /* lalinuna.de 04.11.2004
             * get id of the book from request
             */
            Integer id = Integer.valueOf(request.getParameter("id"));
                    // [laliluna] 28.11.2004 get business logic
            LibraryManager libraryManager = new LibraryManager();
//!!!!!!!! the setBean occures here
bookEditForm.setBook(libraryManager.getBookByPrimaryKey(id));
            return mapping.findForward("showEdit");
    }

If I try the set(String, Object) method of DynaValidatorForm, I recive
only an error :
    public ActionForward editStatus(
            ActionMapping mapping,
          ActionForm form,
          HttpServletRequest request,
          HttpServletResponse response){

        sessHib = HibernateUtil.getSessionFactory().getCurrentSession();
        sessHib.beginTransaction();
        DynaValidatorForm frmDynaStatus= (DynaValidatorForm) form;
      long id = Long.parseLong(request.getParameter("id"));

      Status status = getStatus( id );
//?????? what is the right way to set the bean here?
frmDynaStatus.set( "formBean", status);

        sessHib.getTransaction().commit();
      HibernateUtil.getSessionFactory().close();

      return mapping.findForward("showEdit");
    }
