Document ability to control validation groups on a button

[weaverryan]

As of Symfony 2.3, the validation_groups option can be set on a button field. So that if you submit using this button, that validation group will be used.

Perhaps this could be doc'ed on the 3 buttons themselves: http://symfony.com/doc/current/reference/forms/types.html#buttons

But it is documented at http://symfony.com/doc/2.3/book/forms.html#groups-based-on-the-clicked-button.

Or do you mean to add another notice on the button field types? But it would only make sense with a submit button I think.

I'd say it makes sense to add a note to the button type too. This could then be linked to the article you linked to.
