PROBLEM:
I select a filter in Views, animation appears and is not deleted.
During filtering, 2 ajax requests are sent.
SETTINGS:
The combination is configured: views + BEF + autosubmit.
CAUSE:
The "views_ef_fieldset" module creates a duplicate of the "submit" button. Autosubmit sees 2 buttons and hangs the send trigger on them. When filtering, "Auto Submit" clicks on two buttons.
DECISION:
When duplicating the "submit" button, we check the attribute of the hidden button: ['#attributes'] ['data-bef-auto-submit-click'], if it exists, then delete it.
Not all content is available!
It's likely this issue predates Contrib.social: some issue and comment data are missing.
I am having the same problem with BEF and search api solr autocomplete. I am going to open an issue on BEF, but I wanted to mention that this issue is more widespread
Marking as needs work as question in #6 unanswered, and patches should now be converted to merge requests.
