Use table_layout gives error

[Burgov]

The twig template below gives me an error:

{% extends "::base.html.twig" %}
{% use 'TwigBundle:Form:table_layout.html.twig' %}

{% block body %}
<form action="{{ path('import') }}" method="post" {{ form_enctype(form) }}>
{{ form_widget(form) }}
</form>
{% endblock body %}

in D:\workspace\...\app\cache\dev\twig\15\c9\9a61cfb1ef972ba94c47561910af.php at line 14

using div_layout.html.twig instead works fine.

As a plus, instead of a nice error, I get:

Notice: Undefined offset: -1 in D:\workspace\...\vendor\twig\lib\Twig\Error.php line 159

{% form_theme form 'TwigBundle:Form:table_layout.html.twig' %} is one way to do this.

You can find a cookbook article @ http://symfony.com/doc/current/cookbook/form/twig_form_customization.html

Ok, that does work, thanks. Still, I feel the error is somewhat out of place, as "use"-ing div_layout works fine.

And apart from that the error handling seems to be faulty here

[stof]

A template is not traitable if it extends another one. The table layout extends the div layout so it does not work.

[stof]

See https://github.com/fabpot/Twig/issues/349

[fabpot]

The error message handling has been fixed (fabpot/Twig@3cf3573 and fabpot/Twig@7e45720).

[Burgov]

Nice. The template error was just me not reading the docs well, so we can close this one :)

[Burgov]

Nice, 6737bd3 makes both methods possible
