Problem/Motivation

Pretty much like before 8.0.x in #2139921: Contextual links can't handle multiple occurrences of the same contextual links, contextual module does not support multiple contextual blocks with the same parameters, although it manifests a bit differently.

When the same content appears more than once on the same page, that content naturally has the same contextual links (specifically, exactly the same contextual links placeholder, e.g. <div data-contextual-id="foo:"></div>). Each contextual link should work correctly and act independently, of course.

However, that is not what happens. In the current codebase, when clicking one contextual link (by clicking on the pencil icon), it does not open. As observed in the chrome devtools, both links receive the event (flashes in the inspector), but none displays.

Steps to reproduce

  • Create a render array in a controller
  • Add a #contextual_links element, pointing to some section with appropriate parameters
  • Add a child element within the top-level render array
  • Within that element, add a similar #contextual_links element, with the same parameters

Go to the page for that controller. The same contextual link now appears twice: once in the main content area, once in the other element further down. Click either contextual link. No contextual link menus will be opened.

Workaround

Add an unused extra route_parameter, with a different value in each element like ['instance' => 1] in the first one, ['instance' => 2] in the second one. The blocks will now work normally, and the links will only carry the extra unused parameter in the query.

This is pretty much how multiple pagers work.

Proposed resolution

Either:

  • Fix this.
  • Or document the workaround

@fgm, thanks for this issue and nice IS. Your workaround also works for me.
We can add key with random (or pseudorandom) value to 'route_parameters' in _contextual_id_to_links(). This will give us the guarantee of the uniqueness of any link. But many tests rely on the ability to predict link value.

So here is another solution. This prevents binding of several javascript object with one html tag. Because the links cease to work due to the fact that when you click on them, several models immediately consider themselves the owners of the pencil icon :)

It seems this reason is also very suitable for #2834346: Contextual links double trigger.

contextual-links_counter_for_unique_id-2891603-8.patch1.54 KB

Could do it server-side as a counter which is a little more predictable for testing? Something like the attached patch? (testing disabled since we know it will break current tests)

@drclaw, thanks for the suggestion. But it seems to me that different id for the same contextual links is a good idea for the contrib module. When for some reason we need to implement different behavior to equal links. But for the core this logic is unnecessary complication.

We just need to eliminate the bug with multiple processing of links (js building links from web-cache, where the problem arises).

Here is the detailed description:

  1. When the page is loaded for the first time, then JS saves all the contextual links to Session Storage (in the browser).
  2. If there are two identical links on the page, they will both in Session Storage without override.
  3. When the page is loaded a second time, the links are taken from the cache, and applied to the related placeholders.
  4. As a result, if there are two placeholders with identical id on the page, than two links will be applied to both of them.
  5. An 'open' event for first link, it is 'close' event for second link. As a result, nothing to shows.

Those, we need just set 1 to 1 relationship between model of contextual links and placeholders (like #5). Or just prevent duplication link ids in Session Storage.

Hey guys,

I've patched this against 8.7.x tree.

I also changed the checks in the JS to use the eq() jQuery method: as this is better for modern browsers, as per jQuery docs (https://api.jquery.com/eq-selector/):

"Because :eq() is a jQuery extension and not part of the CSS specification, queries using :eq() cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. For better performance in modern browsers, use $("your-pure-css-selector").eq(index) instead."

Not sure I fully-grok the what/how/why of this approach. I've updated front-end approach in #2834346: Contextual links double trigger and it seems to be working.

If someone has a good explanation of the backend approach on this issue or has strong opinions about one over the other, I'd love to hear.

Tested the patch in #19, works great. Since we have a test-only patch that fails, and several has tested this solution to be OK, this should probably be marked as RTBC. But it has some coding standard errors in the test class, so here is an updated patch.

Last patch had some leftover diff from another issue so ignore that.

It did however show a new test failure, so here is a new patch adressing that.

If you tested and reviewed the patch you might also consider changing the status of the issue to "reviewed and tested by the community"? :)

The patch needed to be rerolled for JS tooling changes in 9.x - I applied #30 without patching core/modules/contextual/js/contextual.js. I then ran:

yarn run lint:core-js-passing --fix
yarn run build:js

As this doesn't change any functionality, and in a better world we wouldn't commit core/modules/contextual/js/contextual.js anyway, leaving at rtbc

So let's fix that too. Same yarn commands run on 8.9.x...
