I want to extend the FormHelper and used this part of a method's code to be called in the view.
$out = parent::input($fieldName, $opts);
return parent::output($out);
Error: Call to a member function useTag() on a non-object File: ...lib/Cake/View/Helper/FormHelper.php Line: 861
The label method :
return $this->Html->useTag('label', $labelFor, $options, $text);
CakePHP version 2.5.1
