Incompatible with Views 6.x-3.x

Hi,
I've installed the latest version of the FullCalendar module together with views 6.x-3.x-dev (2011-Jan-21). and created a view for fullcalendar (exported view see below). But the view doesn't work. Always, this error message will be shown in a messagebox:

An error occurred at /admin/build/views/ajax/preview/FullCalendar.
Error Description: 
Fatal error:  Call to undefined method fullcalendar_plugin_display_page::render_textarea() in C:\xampp\htdocs\drupal\sites\all\modules\fullcalendar\fullcalendar_plugin_display_page.inc on line 16

My content type "Event" has a datetime field. I've created a node view, set the view style to "FullCalendar" and the view row style plugin to "Node - FullCalendar".

Any idea?

Here is my view:

$view = new view;
$view->name = 'FullCalendar';
$view->description = '';
$view->tag = '';
$view->base_table = 'node';
$view->human_name = '';
$view->core = 6;
$view->api_version = '3.0-alpha1';
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */

/* Display: Defaults */
$handler = $view->new_display('default', 'Defaults', 'default');
$handler->display->display_options['access']['type'] = 'none';
$handler->display->display_options['cache']['type'] = 'none';
$handler->display->display_options['query']['type'] = 'views_query';
$handler->display->display_options['exposed_form']['type'] = 'basic';
$handler->display->display_options['pager']['type'] = 'full';
$handler->display->display_options['style_plugin'] = 'fullcalendar';
$handler->display->display_options['style_options']['display']['fc_firstday'] = '1';
$handler->display->display_options['style_options']['modules']['fc_theme'] = 0;
$handler->display->display_options['style_options']['modules']['fc_url_colorbox'] = 0;
$handler->display->display_options['style_options']['times']['fc_clock'] = 1;
$handler->display->display_options['row_plugin'] = 'fullcalendar_node';
/* Filter: Node: Type */
$handler->display->display_options['filters']['type']['id'] = 'type';
$handler->display->display_options['filters']['type']['table'] = 'node';
$handler->display->display_options['filters']['type']['field'] = 'type';
$handler->display->display_options['filters']['type']['value'] = array(
  'event' => 'event',
);

/* Display: FullCalendar */
$handler = $view->new_display('fullcalendar', 'FullCalendar', 'fullcalendar_1');
$handler->display->display_options['pager']['type'] = 'some';
$handler->display->display_options['path'] = 'fullcalendar';
$translatables['FullCalendar'] = array(
  t('Defaults'),
  t('more'),
  t('Apply'),
  t('Reset'),
  t('Sort By'),
  t('Asc'),
  t('Desc'),
  t('Items per page'),
  t('- All -'),
  t('Offset'),
  t('FullCalendar'),
);
