TextType empty_data = null if string is empty

Bug report?	yes
Symfony version	3.2.4

Hello.

I am getting null value after passing empty string to symfony form field.
After defining empty_data in form builder, the problem has gone:

        $builder
            ->add('name', TextType::class, [
                'empty_data'  => '',
            ])

But documentation claims that empty_data is empty string ('') by default. So either the documentation should be changed or behavior of form field type.

Link to docs: http://symfony.com/doc/current/reference/forms/types/text.html#empty-data

Thanks.

The feature has been introduced in 3.1 in symfony/symfony#18357, but the target should now be 3.2. It would be easier to handle it once #6265 is merged.

Why was this put on hold? More people are running into this, see symfony/symfony#22192

Hi @curry684, I've changed the label, see ##6265, empty_data option needs a revamp, and some more work on symfony 2.7. I've changed the label to better indicate the status.

I have just encountered this bug. Is it a problem in the documentation or do you intent to change the behavior of the TextType?

[HeahDude]

The behavior is now null by default or empty string if explicitly configured (which not possible before symfony/symfony#18357), this cannot change for BC.

But it may be the opposite in 4.0, I'm working on it (no PR is open yet) but this is not as simple as it sounds :).
