How To Enable Eager Loading For Stat Relations

I have problem in eager loading of stat query (criteria), I have used the "together" property of criteria and

observed that eager loading worked for non-stat relations, but for stat relation it is not working.

Is it that eager loading can not be expected for stat relations?

If you have any solution please share.

Thanks in advance.

Following is the code for criteria

 $criteria->with = array(

            // 1. Non-STAT relation

            'pl_sports' => array('joinType'=>'LEFT JOIN',



            // 2. STAT relation 

            'total_rating' => array(

                'joinType'=>'LEFT JOIN'



  $criteria->together = true; // Enables eager loading for relation 1 only
