Breadcrumb trail not applied if another module calls drupal_get/set_breadcrumb() early

thanks @longwave - exactly what i needed!

@longwave, great work! I am using Menu Position with Menu Breadcrumb, and the breadcrumb wouldn't show up, but the patch made it appear. Without the title, though, even though I have 'Append page title to breadcrumb' selected in Menu Breadcrumb settings. But I have a breadcrumb and that's what counts.

Thanks, this patch helps with Menu Breadcrumb. As I add the page title through the theme (Zentropy) it works perfect.

Patch works, but Menu Breadcrumb cannot add page title. Can something be done about it in Menu Breadcrumb module? I also tried to edit module weights, but that does not help.

Work also for panel paths like 'node/%node/article'

Yup, works for me with menu breadcrumbs as well. Marking "reviewed and tested" since it seems like we've got a few folks reporting success.

Patch updated to use paths relative to the module directory. Great work on this one, just what I needed.

Changing modules weight has no effect because of this :

/**
 * Implements hook_page_delivery_callback_alter().
 *
 * This is the only hook that occurs after the page callback, but before
 * hook_page_build (when blocks are added). We're using this hook for its
 * timing, not its data.
 */
function menu_position_page_delivery_callback_alter() {
  //...
}

Perhaps menu_position should give a chance to other modules to alter the breadcrumb (like adding the current page title).
This could be done inside this function, by adding a drupal_alter() before setting active trail :

function menu_position_activate_rule($rule, $context, $set_breadcrumb) {
  //...
    drupal_alter('menu_position_active_trail', $active_trail, $context);
    menu_set_active_trail($active_trail);
  }

  return TRUE;
}

However, should menu_position prevail over all other breadcrumb related modules?
Using menu_position makes all other modules useless.

The patch in #7 works fine for me. (I have no problem with the title, it's added to the bc trail)

Patch in #7 works for me using Panels and solves my problem in this context.

Patch in #7 works for me

Upping priority as the patch is 5 months old.

+1 for RTBC (using this in production)

Please lets get #7 in.

#8: An alter hook is a nice idea.

Overriding other modules is no problem, because you can select _when_ to apply menu position rules. Want another module? Just don't use mpr on this path.

+1 for #7. Work for me too

The patch in #7 solved an issue of the breadcrumb not appearing in a panel. Yay!

Patch in #7 had whitespace issues for me. Re-rolled.

Sorry, path issues in that one.

Patch in #7 works for me using Adaptive Theme with options "Append the page title to the breadcrumb trail" enabled. Without this patch only page title was showing in the breadcrumbs without menu trail.

#16 solved the problem for me.

Yep, another rtbtc by me :)

Mine broke when using special menu items which was setting the trail.

Normally, I would not consider this a critical priority issue as there are not any wsod (white screens of death) or data loss. But this is really major as it is not actually working without it!

Solved my problem as well.

Another RTBC here. Fixes the conflict with items nested under a special menu item.

RTBC here as well. This fixed my breadcrumb issues.

RTBC, resolves my issues.

#16 fixed my problem with the breadcrumb as well. Someone please commit this.

RTBC, resolves my issues. thanks.

RTBC bump :)

#16 solved the problem for me.

#16 works for me to, +1 on RTBC

Um. "Me Too". This has been an issue forever...Would LOVE to see this committed!!!!

Not using special menu items, but whatever what was causing the problem was fixed by this patch

RTBC-ed 3 years ago. Patch fixes the issue for a lot of people. Can this please be committed?
I'm happy to become co-maintainer if time is the issue here.

Thank you! #16 solved my problems

This is already set to critical, so hope the maintainer look at here soon.

ps. RTBC is for #16

Committed and pushed to 7.x-1.x-dev. Thanks all!
