CakePhp : unable to include custom CookieHelper to another custom RecordingHelper ?

Hello, I want to create list view and expanded view ('cookie' =>'Posts.posts' & 'value' = 'list' or 'expanded') with (attr) class => active but getting error when I use CookieHelper function read();

please help?

below are the snapshot 

Unable to Load index file when calling RecordingHelper as <?php echo $this->Recording->toggleLink('list','Posts.post','list'); ?>

and when I remove read(); it's shows me list view and expanded view but not creating any cookie rather redirecting me to path specified.
