 /**
  * Renders a template.
  *
  * 1. This function first looks for a block named "_<view id>_<section>",
  * 2. if such a block is not found the function will look for a block named
  *    "<type name>_<section>",
  * 3. the type name is recursively replaced by the parent type name until a
  *    corresponding block is found
  *
  * @param FormView  $view       The form view
  * @param string    $section    The section to render (i.e. 'row', 'widget', 'label', ...)
  * @param array     $variables  Additional variables
  *
  * @return string The html markup
  *
  * @throws FormException if no template block exists to render the given section of the view
