Subject

I have a class HistoryRecord from which a class CollaboHistoryRecord inherits. I have declared and admin for class A in the following way:

    admin.history_record:
        class: App\Admin\HistoryRecordAdmin
        arguments: [~, App\Entity\History\HistoryRecord, ~]
        tags:
            - { name: sonata.admin, manager_type: orm, group: admin, label: HistoryRecord }
        public: true
        calls:
            - method: setSubClasses
              arguments:
                - historyRecord: App\Entity\History\CollaborationHistoryRecord

In the admin I have the following in the configureFormFields method:

       ....
        $subject = $this->getSubject();
        if ($subject instanceof CollaborationHistoryRecord) {
            $formMapper->add('collaboration', ModelAutocompleteType::class, [
                'property' => ['person'],
                'class' => 'App\Entity\Collaboration'
            ]);
        }

The problem happens when I try to use the autocomplete field: a 500 error happens with the following message:

The field "collaboration" does not exist.

Steps to reproduce

1. Create an entity A and an entity B which inherits from A. Add to entity B a ManyToOne field related to other entity (called C).
2. Create an admin for A using the hability of SonataAdmin to handle inhertied classes.
3. Declare an autocomplete field for the relationship between B and C
4. Try to search a C object

Expected results

5. Get the C object attached to the field

Actual results

RuntimeException:
The field "collaboration" does not exist.

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?

I had a similar issue with conditions in configureFormFields. When autocomplete runs $this->getSubject() is null. This is how I solved it:

    /**
     * {@inheritdoc}
     */
    protected function configureFormFields(FormMapper $formMapper)
    {
        $editSubject = $this->id($this->getSubject());

        //...
        // Show only when edit or autocomplete items action
        if ($editSubject || 'sonata_admin_retrieve_autocomplete_items' === $this->getRequest()->get('_route')) {
            $formMapper
                ->add('myField', ModelAutocompleteType::class, [
                     //...
                    'callback' => [$this, 'myCallback'],
                ]);
            //...
        }
      }
      //...
}

I am experiencing exactly the same as the topic starter in combination with inherited class.
