CloneEntity sets the cloned entity as the event's entity

Created on 9 June 2025, about 1 month ago

Problem/Motivation

I have an entity type (Request) that includes a Paragraph field (Policy). When the user is presented with the creation form for that request, I want the form's paragraph field prefilled with a previously used policy. This is not desired if you are cloning a referenced field entity as it will set that entity as the form's entity.

Steps to reproduce

So I used the Entity prepare form event to clone the policy paragraph (I don't want to reuse the *same* paragraph). The problem is that CloneEntity contains the following code:

    if ($this->event instanceof ContentEntityPrepareForm) {
      $this->event->setEntity($newEntity);
    }

Proposed resolution - User interface changes

It would be nice if there were a checkbox to select - or even better decide based on the context.

This behaviour is by design, just not properly documented. We should definitely state that in the plugin description. This has been developed as part of the Drupal CMS project, where a node edit form gets requested, which requires the cloned entity in the form.

Your suggestion to resolve this with a checkbox sounds great. This would keep the current behaviour, make it obvious to the user what's happening, but also provide flexibility if you need to turn this off.
