Trouble Sorting With Related Model Using Clistview

Hi,

I’ve been working with presenting data. I’m having a slight problem trying to sort the data with a related model column.

Here is my code, if anyone could point me in the right direction that would be great.

Controller




	public function actionIndex($id)

	{

				

		$dataProvider=new CActiveDataProvider('Area', array(

			'criteria' => array(

			'with' =>'areaItems',

			'condition' => 't.id=:area_id',

			'params' => array(':area_id'=>$id)

 		),

			'sort'=>array(

			'attributes'=>array(

				'title'=>array(

				'asc'=>'title',

				'desc'=>'title DESC'

			  ),

			  	'price'=>array(

			  	'asc'=>'price',

				'desc'=>'price DESC'

			  )

		 )

	),

			'pagination'=>array(

				'pageSize'=>5,

			)

 ));		

		

		$this->render('index',array(

			'dataProvider'=>$dataProvider,

		));



My view




<?php $this->widget('zii.widgets.CListView', array(




	'dataProvider'=>$dataProvider,

	'itemView'=>'_view',

	'sortableAttributes'=>array(

        'title', 'price'

    ),


)); 



My relations are:




 'areaItems' => array(self::HAS_MANY, 'Item', 'area_id') // Area Model

 'Area' => array(self::BELONGS_TO, 'Area', 'area_id') // Item Model



When I try to sort the results I get the following error: CDbCommand failed to execute the SQL statement: SQLSTATE[42S22]: Column not found: 1054 Unknown column ‘title’ in ‘order clause’.

I should also mention that i’ve tried referencing the table directly and through the relation like areaItems.title but I still get the following error.

Thanks in advance for any solutions
