This image captures the bug. It shows a Drupal 8 site on the /admin path. The debugger is paused on line 53 contextual.toolbar.js. In this case, we are trying to access Drupal.contextual.collection, but Drupal.contextual is not defined.

Only local images are allowed.

Here's the patch that fixes it. We need to check for Drupal.contextual before accessing Drupal.contextual.collection.

There already is a follow-up patch on the issue that introduced this: #1971108-36: Convert contextual.js to use Backbone (and support dynamic contextual links). It solves it very differently though. This is slightly more complex, but also better for front-end perf.

Let's figure out the best solution here.

I'm more for something like #1 than adding the dep to the script.

Same fix as in #1 with a nicer syntax.

If it wasn't for #1639012: Guard against broken behaviors it'd be a critical bug :p


I only found it because I run hacked core JS to expose stuff like this.

turns out #914382: Contextual links incompatible with render cache fixed it so it's all good.

Status:Closed (works as designed)» Needs work

#9: actually, the solution applied in #914382: Contextual links incompatible with render cache is suboptimal, as you already said in #3. So this patch should still be rerolled, and should remove the dep introduced by #914382: Contextual links incompatible with render cache.

Umm, sure, but in contextual_page_build there is

  $page['#attached']['library'][] = array('contextual', 'drupal.contextual-links');

Which means that it'll be on the page regardless.

Anyway, here is the patch. Made into an anonymous function otherwise a js checking tool complains about a function defined in a if (because of hoisting and that sort of things).

You're right. But it's possible that somebody removes the library in hook_page_alter() for some reason, and then thanks to #11 we still won't break. So it's still better :)
