Currently, the adapters for the Templating component reside in the Form component (to be precise, in Symfony\Component\Form\Extension\Templating) but the relevant templates are still located in FrameworkBundle. They should be moved to the Form's Templating extension before 2.2 to decouple Form from FrameworkBundle.

Plan

• move view files to Form/Resources/views/
• move FormHelper to Form/Extension/Templating/
• make TemplateNameParser in FrameworkBundle accept namespaces ([FrameworkBundle] Made TemplateNameParser able to parse templates in the @-notation (#5660) #7818).
• add "Form" namespace pointing to the Form component in FrameworkBundle
• replace "FrameworkBundle:Form" and "FrameworkBundle:FormTable" by "Form:DivLayout" and "Form:TableLayout" in TemplateNameParser
• add TemplateNameGeneratorInterface to Form/Extension/Templating/ (see below)
• create a TemplateNameGenerator in the Form component that is compatible with TemplateNameParser in the Templating component
• create a TemplateNameGenerator in FrameworkBundle that is compatible with TemplateNameParser in FrameworkBundle
• make TemplatingRendererEngine::loadResourceFromTheme use the TemplateNameGenerator

namespace Symfony\Component\Form\Extension\Templating;

interface TemplateNameGeneratorInterface
{
    // e.g. ->generate('FrameworkBundle:Form', 'form_widget_simple')
    // or ->generate('/path/to/Form/Resources/views/Form', 'form_widget_simple')
    public function generate($theme, $block);
}
