The formUpdated event isn't triggered when selecting an option from the autocomplete suggestion list. This problem only exists when using the selection dropdown, while typing in the actual textfield the event triggers nicely.

Proposed resolution

Explicitly triggering the formUpdated event from the selectHandler seems to be the most straight forward solution.

Remaining tasks


User interface changes


API changes


Data model changes

"selectHandler" handler is overrideable. Should we trigger it via a jQuery UI event?

Placed inside Drupal.behaviors.autocomplete.attach?

Drupal 8.2.6 was released on February 1, 2017 and is the final full bugfix release for the Drupal 8.2.x series.
