CGridview and buttons problem

I have this CGridview and when i insert the buttons column i get a parser error inside the column:


$this->widget('zii.widgets.grid.CGridView', array(

    'id' => 'encomenda-linha',

    'dataProvider' => $encomendaLinhasProvider,

    'htmlOptions' => array('style' => 'padding:0'),

    'columns' => array('ritmo.artist',

        'ritmo.title',

        array(

            'header' => Yii::t('app', 'Price'),

            'name' => 'ritmo.price',

            'htmlOptions' => array('style' => 'width:10px;'),

            'value' => '$data->ritmo->price." €"'

        ),

        array(

            'class' => 'CButtonColumn',

            'template' => '{delete}',

            'buttons' => array(

                'delete' => array(

                    

                    'url' => Yii::app()->createUrl('enclinha',array('id'=>'2')),

                    'imageUrl' => Yii::app()->request->baseUrl . '/images/cross.png',

            )),

        )

    )

));

Parse error: syntax error, unexpected ‘/’ in D:\xampp\htdocs\StyleStore\framework\base\CComponent.php(607) : eval()'d code on line 1

Check the documentation for the buttons property - http://www.yiiframework.com/doc/api/1.1/CButtonColumn#buttons-detail

the "url" options should be a PHP expression!

Thank you.Is it possible to turn this button non ajax?
