magento - fatal error : Call to a member function toOptionArray() on a non-object in Magento admin

Question

当我单击 Magento 系统 -> 配置 -> 销售选项卡下的发货方式选项卡时，我遇到以下错误:

Fatal error: Call to a member function toOptionArray() on a non-object in D:\xampp\htdocs\magento\app\code\core\Mage\Adminhtml\Block\System\Config\Form.php on line 463

最令人震惊的是，这是 Magento 的全新安装。谁能告诉我如何消除这个错误？

添加到config.xml

<global>
    <models>
        <stockindicator>
            <class>Namespace_ModuleName_Model</class>
        </stockindicator>
    </models>
</global>
