[Symfony 4.2] Twig failed to render the widget

[ihortymoshenko]

Hi!

I'm updating a project from Symfony 4.1 to Symfony 4.2 and I'm faced with a problem.

Twig can't render the widget and outputs the following:

An exception has been thrown during the rendering of a template ("Notice: Array to string conversion").

The last step in the traceback refers to https://github.com/symfony/twig-bridge/blob/v4.2.7/Resources/views/Form/form_div_layout.html.twig#L432.

It looks like the issue in the form type options. The attr option contains the options key which is an array (the attr option is an associative array with HTML attributes as keys accordingly to the Symfony docs).

Please fix this issue.

Cheers!

This is still an issue with version 1.5.15 on Symfony 4.3.x.

@IgorTimoshenko Did you manage to fix this issue in your project? I'm having the same problem.
