ColdFusion 10中的標籤嵌套配置無效？

我該如何解決這個ColdFusion錯誤？我跟隨this ColdFusion教程。當我試圖實現的ColdFusion 10的代碼，我得到了以下錯誤：ColdFusion 10中的標籤嵌套配置無效？

Invalid tag nesting configuration. A query driven queryloop tag is nested inside a queryloop tag that also has a query attribute. This is not allowed. Nesting these tags implies that you want to use grouped processing. However, only the top-level tag can specify the query that drives the processing.

The error occurred in line 76

74 : </cfloop>

75 : </tr>

76 : <cfoutput query="data" startRow="2">

77 : <tr>

78 : <cfloop index="c" list="#colList

下面是代碼：

<cfset showForm = true> 
<cfif structKeyExists(form, "xlsfile") and len(form.xlsfile)> 

    <!--- Destination outside of web root ---> 
    <cfset dest = getTempDirectory()>

    <cfif upload.fileWasSaved>

     <cfif isSpreadsheetFile(theFile)> 
      <cfspreadsheet action="read" src="#theFile#" query="data" headerrow="1"> 
      <cffile action="delete" file="#theFile#"> 
      <cfset showForm = false>

是所有的應該是一段代碼，你還沒有付錢給格式化，或者你是否試圖通過格式化來傳遞某種信息？ –

這真的是產生錯誤的代碼嗎？我認爲不是，因爲上面不包含任何嵌套的查詢循環。 – Leigh

無論您運行什麼代碼來獲取該錯誤，它都不是您在上面發佈的代碼，也不是Ray的博客上的代碼。發佈您正在運行的實際代碼。該代碼中沒有嵌套輸出。 –

試試這個：

<cfoutput> 
    <cfloop query="data" startRow="2"> 
     <tr> 
     <cfloop index="c" list="#colList#"> 
      <td>#data[c][currentRow]#</td> 
     </cfloop> 
     </tr>      
    </cfloop> 
</cfoutput>
