Symfony2 Assetic: duplicates combined content of JS files in dev environment

I have set up assets in my config.yml:

assetic:
    debug:          '%kernel.debug%'
    use_controller: '%kernel.debug%'
    filters:
        cssrewrite: ~

On twig template JS files are loaded:

    {% block javascripts %}
        {% javascripts output="assets/js/app.js"
            '@AppBundle/Resources/public/js/thirdparty/jquery-3.1.1.min.js'
            '@AppBundle/Resources/public/js/thirdparty/bootstrap.min.js'
            '@AppBundle/Resources/public/js/thirdparty/bootstrap-select.min.js'
            '@AppBundle/Resources/public/js/forms.js'
             %}
            <script src="{{ asset_url }}"></script>
        {% endjavascripts %}
    {% endblock %}

The issue is: In dev environment there are 4 separate requests to these files, but each one is combined with others (what should be done ONLY in prod environment):

Seems like some misconfiguration, but have no idea what exactly.

P.S. In prod environment eveything OK - there is only 1 request for combined file.

P.S.S. Symfony version is 2.8.12

Solution

  • Solved by reinstalling symfony/assetic-bundle.

    Still have no idea what was wrong.
