I am using Captcha component with cakephp 2.0. Though Its going well but my traced issue with this component.

```
Warning: Argument 1 passed to Component::__construct() must be an instance of ComponentCollection, none given, called in ...

```

When I tried to find solution it gives me two line code in somewhere comment.

```
_controller = $collection->getController();
parent::__construct($collection, $settings);

function startup( ) {
     $this->Controller = $this->_controller;
}

```

The solution code is something like this which ended me with error.
