Incompatibility with Display Suite?

This sounds strange, because we don't use the flexible layout plugin from panels.

Thanks for this hint, I've been searching for hours now.

Tested this way (using simplytest.me - great helper!)

1. installed spark + display suite
2. logfile: looks fine
3. enabled display suite
4. logile: 4 notices, 4 warnings

Notice: Undefined index: items in panels_flexible_panels() (line 257 of /home/seb915089fa41c33/www/profiles/spark/modules/contrib/panels/plugins/layouts/flexible/flexible.inc).
Warning: Invalid argument supplied for foreach() in panels_flexible_panels() (line 257 of /home/seb915089fa41c33/www/profiles/spark/modules/contrib/panels/plugins/layouts/flexible/flexible.inc).

Maybe this issue should rather be placed in spark's issue queue?

Apply the two patches to make layout module compatible with display suite.
layout-1.0-compatibility_with_display_suite.patch is for layout module, ds-2.6-support_responsive_panels_of_layout.patch is for ds module.

Thank you, patches of #4 fixed the errors for me.

Here's an updated patch for Display Suite against version 2.10.

This patch also reorders the $content array so regions render in the proper order. Previously, if a region's key matched the field name (e.g., "body" field), it's content would not necessarily render in the proper order within the responsive layout. I'm not sure this is the best place or best way of doing this, but it works.

What are the best steps to get both of these patches absorbed into their respective modules? I would presume an issue should be opened under Display Suite with it's patch.

Hi! Thanks for the patchs! but don't work in my installation. Also the errors are a little different:

Notice: Undefined index: regions in layout_responsive_panels() (line 147 of /sites/all/modules/layout/plugins/layouts/responsive.inc).

Warning: Invalid argument supplied for foreach() in layout_responsive_panels() (line 147 of /sites/all/modules/layout/plugins/layouts/responsive.inc).

The errors refer to this code snippet:

/**
 * Return the actual list of regions for this responsive panel.
 */
function layout_responsive_panels($display, $settings, $layout) {
  $items = array();
  layout_responsive_merge_default_settings($settings, $layout);

  // Resolve machine names to names for visual presentation in panels.
  $default_regions = layout_region_load_all();
  $region_names = array();
  foreach ($settings['regions'] as $name => $overrides) {
    $region_names[$name] = $default_regions[$name]->admin_title;
  }

  return $region_names;
}

Suggestions?
