Path 'admin/structure/types/manage/%/panelizer' is inaccessible

The Comment module is enabled. Disabling it has no effect.

I'm using a brand-new Drupal install (7.26) with the 'Standard' install profile. The issue persists in the '7.x-3.x' branch as of commit 104488cb91da2c28d03ae80aff46fc5978238650 (Issue #1965148 by DamienMcKenna, fago, das-peter: Don't save records for default...)

Commit 89c91da764f1824d5d3c7febd2f602eeab620aae doesn't appear to modify the behavior described by this issue.

The issue is related to the new 'PanelizerEntityComment' class. Line 13 in 'plugins/entity/PanelizerEntityComment.class.php' is of interest because this is the same path reported by this issue:

 7 /**
 8 * Panelizer Entity comment plugin class.
 9 *
10 * Handles comment specific functionality for Panelizer.
11 */
12 class PanelizerEntityComment extends PanelizerEntityDefault {
13   public $entity_admin_root = 'admin/structure/types/manage/%';
14   public $entity_admin_bundle = 4;
15   public $views_table = 'comment';
16   public $uses_page_manager = FALSE;
17
18   public function entity_access($op, $entity) {
19     if ($op == 'edit') {
20       return comment_access($op, $entity);
21     }
22     // The view operation is not implemented by core.
23     if ($op == 'view') {
24       return TRUE;
25     }
26
27     return FALSE;
28   }

When I modify line 13, the symptom described by this issue is no longer present; however, I don't know how resolve this issue in a way that doesn't break the new Comment functionality.

Line 17 from 'plugins/entity/PanelizerEntityNode.class.php' may be instructive:

17 public $entity_admin_root = 'admin/structure/types/manage/%panelizer_node_type';

This issue remains unresolved. I don't believe line 13 is necessary:

plugins/entity/PanelizerEntityComment.class.php

13  public $entity_admin_root = 'admin/structure/types/manage/%panelizer_node_type';

I dug a little deeper into plugins/entity/PanelizerEntityDefault.class.php:

159  /**
160   * Base class for the Panelizer Entity plugin.
161   */
162  abstract class PanelizerEntityDefault implements PanelizerEntityInterface {
163    /**
164     * Where in the entity admin UI we should add Panelizer tabs with bundles.
165     */
166    public $entity_admin_root = NULL;

The Comments entity type doesn't have an admin UI where Panelizer tabs would be added, correct?

Further, when line 13 is included, there is undesired behavior:

• The Panelizer tab on nodes is no longer available
• e.g. admin/structure/types/manage/page
• Export tab is missing from content type Panelizer default config page
• See attached screenshot
• e.g. admin/structure/types/manage/page/panelizer/default/%/settings
• Duplicate sub-tabs on content type Panelizer default config page
• See attached screenshot
• e.g. admin/structure/types/manage/page/panelizer/default/%/settings
• When clicked, duplicate sub-tabs result in invalid path and a 403 error

Patch to remove '$entity_admin_root' from 'PanelizerEntityComment.class.php'

The patch from #12 doesn't appear to have an affect on the symptoms described by this issue. It does result in a new error, however:

Warning: str_replace() expects at least 3 parameters, 2 given in PanelizerEntityComment->add_admin_links() (line 88 of /var/aegir/platforms/cu_platform_2-x_5/sites/example.com/modules/panelizer/plugins/entity/PanelizerEntityComment.class.php).

The patch from #13 corrects the symptoms described by this issue.

Regarding #16, I tested patch #12 and patch #13 independently. Should I be testing with both patches being applied successively (with patch #17 replacing #13)?

I downloaded the latest dev release and applied patch #17. Testing was successful. Thanks.
