drupal_static_reset causing errors

Question

I have developed a custom template for a node where I wanted to essentially show the node in a blank white page. I created a file called node--results.tpl.php and page--node--results.tpl.php that removed just about everything except a few divs. In my module, I have function called results_view_preprocess_node that adds the custom javascripts and css files I needed and removed.

function results_view_preprocess_node(&$variables) {

  if ($variables['view_mode'] == 'full') {
    $node = &$variables['node'];
    if ($node->type == 'results') {
      //remove all other CSS files
      drupal_static_reset('drupal_add_css');

      $path = drupal_get_path('module','results_view');
      drupal_add_css($path . '/css/styles.css');
      drupal_add_css('sites/all/libraries/jquery/jquery-ui-1.10.4.custom/css/smoothness/jquery-ui-1.10.4.custom.min.css');
      drupal_add_js('/sites/all/libraries/jquery/jquery-ui-1.10.4.custom/js/jquery-ui-1.10.4.custom.min.js');

      $id = $variables['nid'];
      drupal_add_js(
        'meetdir="/files/results/' . $id .'";',
        array(
          'type' => 'inline',
          'scope' => 'header',
          'weight' => 5,
          'group' => JS_LIBRARY,
        )
      );

      drupal_add_js(
        array(
          'results_view' => array(
            'path' => drupal_get_path('module','results_view'),
          ),
        ),
        'setting'
       );
      drupal_add_js(
        $path . '/js/advancedResults.js',
        array(
         'type' => 'file',
         'scope' => 'header',
         'group' => JS_LIBRARY,
        )
      );
      drupal_add_js(
        $path . '/js/filter.js',
        array(
          'type' => 'file',
          'scope' => 'header',
          'group' => JS_LIBRARY,
        )
      );

      //drupal_set_message('<pre>' . print_r($variables,true) . '</pre>','warning');
    }

  }
}

I've noticed that when I load a node of this type, I get a large number of warnings and have narrowed it down to drupal_static_reset('drupal_add_css');. When I comment this line out, I don't get the warnings, but then I don't get a clean page.

As far as I have been able to tell, this is the technique you're supposed to use to create a separate template for a node, but obviously, I'm missing something. What do I need to do to fix this?

EDIT Looking at the rendered HTML, both CSS files I add using drupal_add_css are linked like this:

<style type="text/css" media="all">
   @import url("http://www.oregonswimming.org/sites/all/modules/results_view/css/styles.css?ngdwh6");
   @import url("http://www.example.com/sites/all/libraries/jquery/jquery-ui-1.10.4.custom/css/smoothness/jquery-ui-1.10.4.custom.min.css?ngdwh6");
   @import url("http://www.example.com/modules/shortcut/shortcut.css?ngdwh6");
   @import url("http://www.example.com/modules/toolbar/toolbar.css?ngdwh6");
 </style>

Answer 1

Well, if group, page, weight etc are missing or undefined, try this :

$file = drupal_get_path('module','results_view') . '/css/styles.css';
drupal_add_css($file, array(
    'type' => 'file',
    'group' => CSS_DEFAULT,
    'every_page' => TRUE,
    'weight' => 0),
    );

Maybe following a drupal_static_reset('drupal_add_css'); calls to drupal_add_css need these attributes. Perhaps the functions defaults get reset as well.

Answer 2

I ended up removing drupal_static_reset('drupal_add_css'); from my code and overriding all the drupal css styles in my own CSS file. It's a pain but the only way I can find to get rid of all the errors.
