Symfony Form Collection won't remove element

Question

Form Type

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
            ......
            ->add('menores', 'collection', array(
                'type' => new CotizacionMenorType(),
                'allow_add' => true,
                'allow_delete' => true,
                'by_reference' => false,
                'required'  => false
            ))
            ......
    ;
}

Controller

public function editarAction(Cotizacion $cotizacion, Request $request)
{

    $pageData['accion'] = 'Editar';

    $objForm = $this->createForm(new EditarCotizacionType(), $cotizacion);

    $objForm->handleRequest($request);

    if ($objForm->isValid()) {
        echo '<pre>';
        echo \Doctrine\Common\Util\Debug::dump($cotizacion->getMenores());
        die('</pre>');
        .............
    }
    .......
}

When I render the form and remove form the DOM 1 element, then I submit the form and the elements still in the coleccion., when I print de $cotizacion->getMenores() the removed element still there

Thanks

在您的关系注释中，请确保已设置orphanRemoval。

@ORM\OneToMany(targetEntity="Image", cascade={"persist"}, orphanRemoval=true)

此错误是由版本2.3.10 https://github.com/symfony/symfony/issues/10256中的错误引起的，感谢A6 Software提供的帮助。
