Add Ajax Handler Cause error in paragraph module

Thanks for reporting this. The only use of Drupal\Core\Site\Settings in ECA is the dynamic event subscriber which is the same in 2.0 and 2.1, which makes me wonder how that error message can be explained.

We do need more details, though.

• Do you have a stack trace in the logs when this error happens?
• How is this related to paragraphs?
• How did you configure to get unique titles?

Adding the ajax handler to the title field is one part, but there needs to be something that validates the unique title, and I don't see how that got implemented at you end. We do need that piece to be able to reproduce the issue.

Also, it sounds like this is similar to 🐛 ECA Form module conflicts with Entity Browser selection in Inline Entity Form Active , can you please have a look? While your report says, there is a difference between the behaviour of ECA 2.0 and 2.1, over there the report sees the difference between 2.0.8 and 2.0.9 - could you please test that with your use case as well?

Thanks jurgenhaas,

You are correct, I just tested and found that this problem appear since 2.0.9.

- Tested 2.0.8 - No Problem
- Tested 2.0.9, 2.0.10 and 2.1.0 - Problem

- How is this related to paragraphs?
I have multiple paragraphs inside a node. I can't click "edit" or "Collapse". Once I clicked, nothing happen and error appear
"Oops, something went wrong. Check your browser's developer console for more details."

- How did you configure to get unique titles?
I do have "Validate Form" but to test this, I just removed Flow from "Validate Form" to check unique title and the problem still there.

Here is how to produce this error:
- Create New Content Type
- Add a Paragraph field inside newly created content
- in ECA, Create Build form -> Form: Add Ajax Handler. (Use the value above to check title)

That's it. When, you click Collapse or add paragraph, error will appear

So, this is likely a duplicate of the related issue. Therefore, can you try the fix I suggested there yesterday?

jurgenhaas,

I just tried to remove $this->plugin->setEcaAction($this); that you suggested here -> ECA Form module conflicts with Entity Browser selection in Inline Entity Form 🐛 ECA Form module conflicts with Entity Browser selection in Inline Entity Form Active

and yes, that appear to solve my problem.

Thank you,

Thanks @abx for testing and your feedback. I'm closing this issue in favour of the other one, where we continue to fixing that bug.
