Erron in ChoiceField

[kevinblo]

Hello. It works fine for rendering form but after SUBMIT I see in storageSource fiels warning "The selected choice is invalid."

            AssociationField::new('carrier')
                ->setRequired(true),

            DependentField::adapt(
                AssociationField::new('cardTemplate'),
                [
                    'callback_url' => $this->generateUrl('admin_card_template_choices'),
                    'dependencies' => ['carrier'],
                    'fetch_on_init' => false
                ]),

            DependentField::adapt(
                ChoiceField::new('storageSource'),
                [
                    'callback_url' => $this->generateUrl('admin_storage_choices'),
                    'dependencies' => ['cardTemplate', 'carrier'],
                    'fetch_on_init' => false
                ]),

I resolve it with setChoises to all possible values and set fetch_on_init => true.
