与自定义属性

Question

分层导航我们有一个分层的导航（screenshot），让我们的用户按类别，价格和颜色过滤。类别和价格工作得很好，因为它们默认为Magento。尝试按颜色（自定义属性）进行过滤时会出现问题。

它引发异常。我能够追踪堆栈轨迹，但我无法理解它。想知道是否有人能帮助我指出正确的方向。跟踪：https://gist.github.com/4490917

我们使用Magento企业v1.12.0.2

有与应用程序/法师/目录/型号/资源/层/过滤器的问题/ Attribute.php

交换以下列出你的课程，并解决它的问题。

你可以简单地从布局下面的例子catalogsearch.xml删除enterprisesearch块：

<catalogsearch_result_index translate="label"> 
    ... 
     <reference name="left"> 
      <remove name="enterprisesearch.leftnav"/> 
     </reference> 
     <reference name="right"> 
      <block type="catalogsearch/layer" name="catalogsearch.rightnav" before="-" template="catalog/layer/view.phtml"/> 
     </reference> 
    ... 
    </catalogsearch_result_index> 

的错误发生，因为他们是两个块做同样的事情在布局。企业搜索在默认情况下存在。
