Asset - allowed extensions fix

Hello,

I fixed the CCK allowed extension validate error. If I use the Asset Wizard, and I choose an mp3 file, using the mp3 formatter, Drupal shows the following error on Submit:
"The selected asset type is not allowed."

Here is the fix, please change to this in asset_content.inc:

function asset_field($op, &$node, $field, &$items, $teaser, $page) {
  switch ($op) {
    case 'validate':
      if ($field['allowed_extensions']) {
        $allowed_extensions = array_map('trim', explode(',', $field['allowed_extensions']));
      }
      
      foreach ($items as $delta => $item) {
        $error_field = $field['field_name'] .']['. $delta .'][aid';
        if (!$item['aid']) {
          continue;
        }
        //BEGIN FIX      
        //$asset = asset_load($item['aid']);
        if (is_numeric($item['aid'])) {
          $asset = asset_load($item['aid']);
        } else  {
          $macros = asset_get_macros($item['aid']);
          $macro = $macros[$item['aid']];        
          $aid = $macro['aid'];
          $asset = asset_load($aid);
        }
        //END FIX
        
        // make sure selected asset is allowed type
        if (is_array($field['allowed_types']) && !$field['allowed_types'][$asset->type]) {
          form_set_error($error_field, t('The selected asset type is not allowed.'));
        }
        
        // make sure selected asset is allowed extension
        if ($asset->type == 'file' && $allowed_extensions) {
          $info = pathinfo($asset->file['filename']);
          if (!in_array($info['extension'], $allowed_extensions)) {
            form_set_error($error_field, t('The selected asset is not one of the allowed extensions.'));
          }
        }
        
        // make sure asset supports one of the valid formatters
        if ($field['valid_formatters']) {
          $valid = FALSE;
          foreach ($field['valid_formatters'] as $format) {
            if ($asset->formatters[$format]) {
              $valid = TRUE;
              break;
            }
          }
          if (!$valid) {
            form_set_error($error_field, t('Asset does not support the specified formatters.'));
          }
        }
      }
      
      break;

    case 'view':
      break;
  }
}
