Notice in _skinr_add_path_to_files when attached CSS or JS file has advanced settings

The css includes take the same arguments as #attached (see docs for drupal_add_css()), so you should have full power over at what point it shows up. Try setting the group to 'CSS_THEME' as well as setting weight.

Marking as fixed. Re-open if still an issue.

Hi,
Sorry to reopen.
I am trying to get this to work to no avail.
The code:

   $css_options = array('group' => CSS_THEME, 'weight' => 999);

  .....................
    'options' => array(
      'button_1' => array(
        'title' => t('Button 1 - arrow'),
        'class' => array('button-arrow'),
		'attached' => array(
		  'css' => array('css/button-arrow.css' => $css_options),
		),
      ),
  ........................

The css output:
css/button-arrow.css (Array, 9 elements)

    group (Integer) 100
    weight (Float) 101.067
    0 (String, 46 characters ) sites/all/themes/mytheme/skins/button/
    type (String, 4 characters ) file | (Callback) file();
    every_page (Boolean) FALSE
    media (String, 3 characters ) all
    preprocess (Boolean) TRUE
    data (String, 20 characters ) css/button-arrow.css
    browsers (Array, 2 elements)
        IE (Boolean) TRUE
        !IE (Boolean) TRUE

The error:

    Notice: Undefined offset: 0 in _skinr_add_path_to_files() (line 935 of G:\xampp\htdocs\drupal7\sites\all\modules\dev\skinr\skinr.module).
    Notice: Undefined offset: 0 in _skinr_add_path_to_files() (line 935 of G:\xampp\htdocs\drupal7\sites\all\modules\dev\skinr\skinr.module).
    Notice: Undefined offset: 0 in _skinr_add_path_to_files() (line 938 of G:\xampp\htdocs\drupal7\sites\all\modules\dev\skinr\skinr.module).

Ref: http://api.drupal.org/api/drupal/developer!topics!forms_api_reference.html/7#attached
Any hint about the issue?

Thanks

UPDATE:
This one doesn't output error, but the weight + group are not applied:
'css' => array('data' => 'css/button-arrow.css', 'group' => CSS_THEME, 'weight' => 999),

Well, looks like you found a bug. Your first example was correct, but the notices shouldn't happen.
Attached is the patch (including tests) that should fix the problem.

Note that there are 3 ways to include a CSS file:

<?php
    'attached' => array(
      'css' => array(
        'skinr_test.css',
        'skinr_test_advanced.css' => array('group' => CSS_THEME, 'weight' => 999),
        array('data' => 'skinr_test_data.css', 'group' => CSS_THEME, 'weight' => 999),
      ),
    ),
?>

Committed. Please re-open if you still have issues.

Thanks a lot. Works great now.

Before the patch I used a swap to the haystack via hook_css_alter:

  // --Move skins css to theme and add heavier weight
  foreach ($css as $key => $value) {
    if (strpos($key, 'skins') !== FALSE) {
      $css[$key]['group'] = CSS_THEME;
      $css[$key]['media'] = 'screen';
      $css[$key]['weight'] = 999;
    }
  }

The patch should allow more granular weights over a group of files as needed. Thanks

Oops, you came early, sorry
