ClistView Yii positionning

Question

I wanted to simplify my views and take advantage of the ClisView features (sorting, paging,...).

(I had foreach to loop on the comments lists and display the list).

To achieve this, I renderPartial my _comments view

$this->renderPartial('_comments',array(
            'dataProvider'=>$dataProvider,

and in my _comments view, in order to list the comments related to a post, I use

<?php $this->widget('zii.widgets.CListView', array(
    'dataProvider'=>$dataProvider,
    'itemView'=>'_comment',
    'template'=>"{items}\n{pager}",
)); ?> 

the _comment view simply contains the following code

<div class="comment">


    <div class="content">
        <?php
            $this->beginWidget('CMarkdown', array('purifyOutput'=>true));
            echo $data->content;
            $this->endWidget();
        ?>
    </div>

</div>

it works fine, it displays the correct data but not in the right place.

To be clear, let say I have 2 posts , POST 1 has 3 comments and POST 2 has 2 comments.

If I click on the POST 1 link to comments, it looks correct, it displays

Post 1 - link to comments

Comment 1 (of post 1)

Comment 2 (of post 1)

Comment 3 (of post 1)

Post 2- link to comments

---

but if I click on the POST 2 link to comments, it displays the following

Post 1 - link to comments

Comment 1 (of post 2)

Comment 2 (of post 2)

Post 2 - link to comments

---

So the comments are displayed under post 1 and not post 2.

I logically expected

Post 1 - link to comments

Post 2 - link to comments

Comment 1 (of post 2)

Comment 2 (of post 2)

---

I must clarify that the list of posts is also displayed by a cListView and when I look to the source code the class names generated are identicals.

here is the code where the dataprovider is defined

$criteria=new CDbCriteria(array(
            'condition'=>'post_id='.$post_id,
            'order'=>'create_time DESC',

            ));
            $dataProvider=new CActiveDataProvider('Comment', array(
            'pagination'=>array(
            'pageSize'=>Yii::app()->params['commentsPerPage'],
            ),
            'criteria'=>$criteria,
            ));
            $this->renderPartial('_comments',array(
            'dataProvider'=>$dataProvider,
        ));

So my question would be, how to ask ClistView to generate different class names ?

Do you know how I can correclty display the comments ?

Thank you in advance for your help
