yii booster checkbox doesn't show boxes to check - checkbox

Question

I add the checkbox functionality from the yii-booster. But the widget renders the model view without the needed boxes. What's wrong?
Widjet code in view
<?php
$this->widget('bootstrap.widgets.TbExtendedGridView',array(
'id'=>'docs-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'type'=>'bordered condensed',
'template' => "{items}",
'bulkActions' => array(
'actionButtons' => array(
array(
'buttonType' => 'button',
'type' => 'primary',
'size' => 'small',
'label' => 'Choose',
'click' => 'js:function(values){console.log(values);}'
)
),
// if grid doesn't have a checkbox column type, it will attach
// one and this configuration will be part of it
'checkBoxColumnConfig' => array(
'name' => 'id'
),
),
));

Answer 1

If you are using bulkActions, you have to use 'columns' to list out the columns you want to display instead of using 'template'.
'columns' => array(
'id',
'title',
...
),

Answer 2

the problem has been in the wrong hierarchy from the example:
The 'checkBoxColumnConfig' attribute must be outside of the 'actionButtons' attribute:
'bulkActions' => array(
'actionButtons' => array(
/*array(
'buttonType' => 'button',
'type' => 'primary',
'size' => 'small',
'label' => 'Выбрать отмеченные',
'click' => 'js:function(values){console.log(values);}'
)
),*/
// if grid doesn't have a checkbox column type, it will attach
// one and this configuration will be part of it
),
'checkBoxColumnConfig' => array(
'name' => 'id'
),
...
));
but now the widget doesn't work when i uncomment the array part inside 'actionButtons':
array(
'buttonType' => 'button',
'type' => 'primary',
'size' => 'small',
'label' => 'Выбрать отмеченные',
'click' => 'js:function(values){console.log(values);}'
)
what might be a cause?
