Description

Given a form type with a date time field using two simple text widget, it is currently not possible to use the error_mapping option on the date and time children.

After some investigation, I found that the DateTimeType defines the error_bubling to true for the date and the time fields. In the example below, when a violation is created, is is mapped to startsAt.date but is bubbled up to startsAt.

https://github.com/symfony/symfony/blob/7.2/src/Symfony/Component/Form/Extension/Core/Type/DateTimeType.php#L166

I could work on a PR as I don't see any easy fix. An option like date_error_bubling/time_error_bubling would do the trick ?
Or should I add date_options/time_options that would override the options passed to these fields ?

Example

$builder
    ->add('startsAt', DateTimeType::class, [
        'date_widget' => 'single_text',
        'time_widget' => 'single_text',
        'error_mapping' => [
            '.' => 'date',
        ],
    ]);
