如何调用Form里DataSource里的method

　Object  FormDataSource;

    FormRun m_form;

    Args    m_args = new Args();

    ;

    m_args.name(formstr(KY_PackageTable_fm));

    m_form = classFactory.formRunClass(m_args);

    m_form.init();

 

//    m_form.run();

//    m_form.detach();

   

    FormDataSource = m_form.dataSource();

    if (FormDataSource && FormDataSourceHasMethod(FormDataSource,identifierstr(method1)))

    FormDataSource.method1();
