Methods in Form were deprecated and will be removed in Symfony 2.3.

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

  • getTypes
  • getErrorBubbling
  • getNormTransformers
  • getClientTransformers
  • getAttribute
  • hasAttribute
  • getClientData
  • getChildren
  • hasChildren
  • bindRequest

  Before:

  $form->getErrorBubbling()
  

  After:

  $form->getConfig()->getErrorBubbling();
  

  The method getClientData has a new equivalent that is named getViewData.
  You can access all other methods on the FormConfigInterface object instead.

  Instead of getChildren and hasChildren, you should now use all and
  count.

  Before:

  if ($form->hasChildren()) {
  

  After:

  if (count($form) > 0) {
  

  Instead of bindRequest, you should now simply call bind:

  Before:

  $form->bindRequest($request);
  

  After:

  $form->bind($request);
