Tbgridview And Render Customized/complex Datacolumns

Hi All,

I am getting the following error:

htmlspecialchars() expects parameter 1 to be string, array given

when trying to do customized/complex datacolumns.

I have the following code:

<?php $this->widget('ext.bootstrap.widgets.TbGridView', array(
    'id'=>'rabbitshow-grid',
    'type'=>'striped bordered condensed',
    'dataProvider'=>$model->search(),
    'filter'=>$model,
    'template'=>"{items}",
    'columns'=>array(
        array('name'=>'show_name', 'header'=>'Show'),
        array('name'=>'show_date', 'header'=>'Date'),
        array('name'=>'judge', 'header'=>'Judge'),
        array('name'=>'StatusText', 'header'=>'Status'),
        array(
            'name'=>'entries',
            'type'=>'raw', //because of using html-code from the rendered view
            //call the method 'gridMemberColumn' from the controller
            'value'=>array($this,'gridEntryColumn'),
        ),
        array(
            'class'=>'CButtonColumn',
        ),
    ),
)); ?>

with gridEntryColumn defined as:

    protected function gridEntryColumn($data,$row)
    {
       $sql = 'SELECT entry_id, name, stud_name, member FROM lag_entry WHERE show_id = ' . $data->show_id .' ORDER BY name';
       $rows = Yii::app()->db->createCommand($sql)->queryAll();

       $result = '1';
       $idx = 1;
       if(empty($rows))
           foreach ($rows as $row)
           {
               $url = Yii::app()->createUrl('entry/view',array('entry_id'=>$row['entry_id']));
               $style = $idx % 2 == 0 ? 'background:#F8F8F8; padding:0.5em;' : 'background:#E5F1F4; padding:0.5em;';
               $text = CHtml::tag('div',array('style'=>$style),$row['name'].' '.$row['stud_name']);
               $result .= CHtml::link($text,$url) .'<br/>';
               $idx++;
           }
       return $result;
    }

now if I replace the TbGridZView with a CGridView it works correctly but I prefer a TbGridView. It appears more to be something to do with searching but I am not positive.

This is part of the stack trace:

Any ideas?
