Unable to add class to form widget

[gelhaimer]

Hello there,

I'm trying to add class attribute to some of my form's widgets.

I tried add this class from both the FormType and the twig template.

{{ form_widget(form, { 'attr' : {'class' : 'my_custom_class' } } }}

The admin bundle set widget's class attribute with "form-control form-control" (which is strange since the class is repeated twice). I would expect both my custom class and the one of the template theme.

As soon as I disable the bundle, my custom class is properly set.

@GregOriz if you could watch the code and find a good solution, please make a pull request for it, I could review it, if not I will try to reproduce and fix more later

@GregOriz could try to reproduce the same behaviour with latest master branch? Thanks
