In CakePHP, I am trying to create a autocomplete function from a textbox, 
using this tutorial: http:
//bakery.cakephp.org/articles/matt_1/2011/08/07/yet_another_jquery_autocomplete_helper_2


I keep getting a

Undefined index: autoCompleteText


I solved the helper issue as it finds the helper as this is cakephp 1.X 
code and I have 2.X


controller - Tests
function auto_complete



class TestsController extends AppController {

public $helpers = array('Html', 'Form', 'Session','Js','AutoComplete');

 public function auto_complete() {
 $this->loadModel('Tutor');
 debug( $this->params);


    $terms = $this->Tutor->find('all', array(
        'conditions' => array(
            'Tutor.first_name LIKE' => 
$this->params['url']['autoCompleteText'].'%'
        ),
        'fields' => array('Tutor.first_name'),
        'limit' => 3,
        'recursive'=>-1,
    ));
    $terms = Set::Extract($terms,'{n}.Tutor.first_name');
    $this->set('terms', $terms);
    $this->layout = '';    
} 



view
 auto_complete.ctp


<?php 
echo $this->AutoComplete->input(
    'Tutor.first_name',
    array(
        'autoCompleteUrl'=>$this->Html->url( 
            array(
                'controller'=>'tests',
                'action'=>'auto_complete',
            )
        ),
        'autoCompleteRequestItem'=>'autoCompleteText',
    )
);

  if(isset($terms)) {
    echo $this->Js->object($terms);
  }

       echo $this->Form->create('');

            echo $this->Form->input('type', array('label' => 'Choose' ));
           echo $this->Form->end('send'); 

 ?>
