Methods in class FormView were deprecated and will be removed in Symfony 2.3.

• The following methods in class FormView were deprecated and will be
  removed in Symfony 2.3:

  • set
  • has
  • get
  • all
  • getVars
  • addChild
  • getChild
  • getChildren
  • removeChild
  • hasChild
  • hasChildren
  • getParent
  • hasParent
  • setParent

  You should access the public properties vars, children and parent
  instead.

  Before:

  $view->set('help', 'A text longer than six characters');
  $view->set('error_class', 'max_length_error');
  

  After:

  $view->vars = array_replace($view->vars, array(
      'help'        => 'A text longer than six characters',
      'error_class' => 'max_length_error',
  ));
  

  Before:

  echo $view->get('error_class');
  

  After:

  echo $view->vars['error_class'];
  

  Before:

  if ($view->hasChildren()) { ...
  

  After:

  if (count($view->children)) { ...
