TbButtonColumn $data error

I'm trying to use $data->id on TbButtonColumn but I'm getting error "Trying to get property of non-object". The TbGridView is working properly! What I'm doing wrong?

View.php:

<?php  $this->widget('bootstrap.widgets.TbGridView',array(
    'type'=>'striped bordered condensed',
    'id'=>'profiles-grid',
    'dataProvider'=>$dataProvider,
    'columns'=>array(
        'id',
        array(
            'class'=>'bootstrap.widgets.TbButtonColumn',
            'template'=>'{create}',
            'buttons'=>array
            (
                'create' => array(
                    'label'=>'Criar Evento',
                    'icon'=>'plus',
                    'url'=>'Yii::app()->controller->createUrl("events/create", array("id"=>$data->id))', // Problem here on $data->id
                ),
            ),
        ),
    ),
)); ?>

Setting the button's url like this worked for me:

'url'=>'$this->grid->controller->createUrl("update", array(
            "id"=>$data->primaryKey))',

The error you're getting is caused by the fact that $data is not an object. You cannot use the property access operator -> on any other variable type.

It is not clear from your question where $data is assigned a value, or what that value is supposed to be. You can ensure a variable contains an object using the is_object function:

if (!is_object($data))
  die('There seems to be a problem with the data');

This will tell you that $data isn't an object, thus preventing the error. BUT, I suspect the underlying problem is whatever mechanism you expect to populate the $data variable is failing, or not working in the way you expect.

You can use var_dump to debug variables and check their type in the process:

var_dump($data);

...this will give you a better idea of what $data actually is -- it isn't an object, that's for sure!
