将订单项目添加到Magento中的订单网格

我正在尝试使用grid.php将订购的产品添加到admin中的订单网格中

app\code\core\Mage\Adminhtml\Block\Sales\Order\Grid.php

我还为此视图添加了另一个客户属性。当我添加产品列表时，找到的订单数总是设置为1，并且它不允许我转到订单的下一页

这是我设法添加的代码

protected function _prepareCollection()
{
    $collection = Mage::getResourceModel($this->_getCollectionClass());
    $collection->getSelect()->join('sales_flat_order_item', '`sales_flat_order_item`.order_id=`main_table`.entity_id', array('name'  => new Zend_Db_Expr('group_concat(`sales_flat_order_item`.name SEPARATOR ", ")')));
    $collection->getSelect()->group('entity_id');
    $collection->getSelect()->joinLeft(
                array('cev' => 'customer_entity_varchar'),
                '(main_table.customer_id = cev.entity_id AND cev.attribute_id = 141 AND main_table.customer_id IS NOT NULL)',
                array(
                    'admin_number' => 'cev.value',
                )
            );

    $this->setCollection($collection);
    return parent::_prepareCollection();
}

   $this->addColumn('admin_number', array(
            'header' => Mage::helper('sales')->__('Admin Number'),
            'filter_index' => 'cev.value',
            'index' => 'admin_number'
    ));

$this->addColumn('name', array(
        'header'    => Mage::helper('Sales')->__('Products'),
        'width'     => '100px',
        'index'     => 'name',
        'type'        => 'text',

    ));

希望有人能帮我找出问题所在。
