title: Paginate component fetches all data not paged data
body: <p>I have a model and i want to paginate its data. all i do is, creating a model, something like this, </p>
  
  <pre><code>class MyModel extends AppModel {}
  </code></pre>
  
  <p>and include Paginator component in my controller and use it, something like this, </p>
  
  <pre><code>class MyControllers extends AppController
  {
  public $components = array('Paginator');
  
  public function index()
  {
  $this-&gt;paginate['MyModel'] = array('limit'=&gt;5);
  print_r($this-&gt;paginate('MyModel'));
  }
  }
  </code></pre>
  
  <p>And I have a table with <code>my_controllers</code> name and it has 10 records. if everything was fine, the paginator component must give me 5 records for page one and 5 records for page 2. but it gives me 10 records without any paging. </p>
  
  <p>What is the problem? :( </p>
  
  <p>Thank you</p>
