I agree with @neurojavi... anybody has a solution?

Maybe my tricky solution would help someone. For views pages i've used hook in custom module, which automatically adds views pages to xmlsitemap on open. It uses xmlsitemap_custom module storage. These pages can be viewed in admin/config/search/xmlsitemap/custom. It is not good way, but it can be basic for further modification or as quick temporary solution.

/**
* Implements hook_views_post_render().
*/
function MYMODULE_views_post_render(&$view, &$output, &$cache) {
  if($view->name == 'display_products') {
    $loc = '';
    // you can get path here for your needs, it is specific to project. i'm using clean urls on views
    if(substr($_GET['q'], 0, '8') == 'catalog/') $loc = $_GET['q'];
    if(substr($_GET['q'], 0, '7') == 'catalog' && isset($_GET['page'])) $loc = 'catalog?' . $_SERVER['QUERY_STRING'];
    if($loc) {     
      if (!db_query_range("SELECT 1 FROM {xmlsitemap} WHERE loc = :loc AND status = 1 AND access = 1 AND language = :language", 0, 1, array(':loc' => $loc, ':language' => LANGUAGE_NONE))->fetchField()) {
        $link = array(
          'type' => 'custom',
          'loc' => $loc,
          'id' => db_query("SELECT MAX(id) FROM {xmlsitemap} WHERE type = 'custom'")->fetchField() + 1,
        );
        xmlsitemap_link_save($link);
      }      
    }
  }
}

Don't forget to add dependencies to module info file:

dependencies[] = xmlsitemap
dependencies[] = xmlsitemap_custom
dependencies[] = views
