Duplicate OneToOne relation by Doctrine and SymfonySeoBundle

Question

I add SEO data to my entity following this article http://symfony.com/doc/current/cmf/bundles/seo/seo_aware.html.

    class Provider implements SeoAwareInterface
    {
        /**
         * @var SeoMetadataInterface
         *
         * @ORM\OneToOne(targetEntity="Symfony\Cmf\Bundle\SeoBundle\Model\SeoMetadata", cascade={"persist","remove"})
         * @ORM\JoinColumn(name="seo_metadata_id", referencedColumnName="id")
         */
        protected $seoMetadata;
    }

I use SonataAdmin to edit Provider entity and I use special form type for seoMetadata property - SeoMetadataType (http://symfony.com/doc/current/cmf/bundles/seo/seo_aware.html#form-type)

protected function configureFormFields(FormMapper $form)
{
    $form
        // some entity related fields
        ->with('form.provider.seo_group_title', [
            'class' => 'col-md-4',
        ])
            ->add('seoMetadata', SeoMetadataType::class, [], [
                'generic_metadata' => false,
            ])
        ->end()
    ;
}

The problem is next - everytime I edit Provider entity I get new record of SeoMetadata.

I've debug updating process and before persist and flush operation I have proxy of SeoMetadata in $seoMetadata property with existed id, but after persist and flush operations I see proxy with new id and new record in table.

Anybody have idea whats wrong?

We do have some ORM examples, but do not fully support it atm. But can you reproduce your issue of persistence only by adding some code here: https://github.com/symfony-cmf/seo-bundle/blob/master/tests/Functional/Doctrine/Orm/SeoMetadataTest.php Simply do a PR and i will try to fix it. But it can also be, that the issue is in sonata or in the forms.
