产品说明更新时出现Magento 1.7索引错误

尝试更新Magento 1.7产品说明时，我们会收到以下错误消息：

Fatal error: Uncaught exception 'Exception' with message '
Warning: Invalid argument supplied for foreach() 
in /app/code/core/Mage/Index/Model/Event.php on line 167' 
in /app/code/core/Mage/Core/functions.php:245

有什么想法吗，出了什么问题

谢谢你的帮助

我也有同样的问题，使用了错误的店铺id

Mage::app()->setCurrentStore(1);
