TYPO3 7.6 Extbase / Fluid form: htmlspecialchars() expects parameter 1 to be string, object given

I have got a form, based on Extbase an Fluid in TYPO3 7.6. Every time a validation error in any field occurs, the form gets displayed again showing the validation errors, as desired. But every time the form gets displayed again and a value has been entered in the date field, the error message htmlspecialchars() expects parameter 1 to be string, object given appears.

I would like to get rid of this error message.

The controller has a date property in it:

<?php

namespace Vendor\Extension\Domain\Model;

class Person extends BaseDto
{
    /**
     * @var \DateTime $privatePersonBirthdate
     */
    protected $privatePersonBirthdate;

    /**
     * @param \DateTime $privatePersonBirthdate
     */
    public function setPrivatePersonBirthdate($privatePersonBirthdate)
    {
        $this->privatePersonBirthdate = $privatePersonBirthdate;
    }

    /**
     * @return \DateTime
     */
    public function getPrivatePersonBirthdate()
    {
        return $this->privatePersonBirthdate;
    }

}

Template:

<f:form.textfield property="privatePersonBirthdate" />

Property configuration in controller:

$conf->forProperty('privatePersonBirthdate')->setTypeConverterOption('TYPO3\\CMS\\Extbase\\Property\\TypeConverter\\DateTimeConverter', \TYPO3\CMS\Extbase\Property\TypeConverter\DateTimeConverter::CONFIGURATION_DATE_FORMAT, 'd.m.Y');

I already found some similar reports online, like https://forge.typo3.org/issues/4268.

The workaround using the value attribute would work, but also destroys the value the user entered in the form on validation errors:

<f:form.textfield property="privatePersonBirthdate" value="{f:format.date(date: person.privatePersonBirthdate, format: 'd.m.Y')}" />

I seems like something is missing. I do not get it. Do you have an idea how to solve this issue?

I solved the issue creating a view helper which converts the property of type DateTime before trying to render it:

<?php

namespace Vendor\Extension\ViewHelpers;

use TYPO3\CMS\Fluid\ViewHelpers\Form\TextfieldViewHelper;

/**
 * This view helper solves the issue described https://stackoverflow.com/questions/45792891/typo3-7-6-extbase-fluid-form-htmlspecialchars-expects-parameter-1-to-be-str
 *
 * Class TextfieldForDatesViewHelper
 * @package Educo\Eddaylight\ViewHelpers
 */
class TextfieldForDatesViewHelper extends TextfieldViewHelper
{
    /**
     * Initialize the arguments.
     *
     * @return void
     * @api
     */
    public function initializeArguments()
    {
        parent::initializeArguments();
        $this->registerTagAttribute(self::DATEFORMAT, 'string', 'Required format for date field');
    }

    /**
     * Converts an arbitrary value to a plain value
     *
     * @param mixed $value The value to convert
     * @return mixed
     */
    protected function convertToPlainValue($value)
    {
        if ($value instanceof \DateTime) {
            return $value->format($this->arguments[self::DATEFORMAT]);
        }
        return parent::convertToPlainValue($value);
    }

    const DATEFORMAT = 'dateFormat';
}
