Coldfusion結構數組錯誤

Question

我想構建數組來存儲報表列名，但我得到了以下錯誤：您試圖解引用類型爲coldfusion.runtime的標量變量。數組作爲具有成員的結構。

我的代碼是：

<cfscript> 
     currentAssetNum = 0; 
     headerLabels  = ""; 
     headerUnderlines = ""; 
     reportContent = ""; 

     columns = eqInventoryHelper.getPreformattedColumnCharacteristics(showComponents = variables.showComponents); 

     // Get an array of the columns in the order they should be displayed. 
     columnOrder = StructSort(columns, "numeric", "asc", "sortOrder"); 

     for (columnName in columnOrder) { 
      //for (columnIndex=1; columnIndex <= StructCount(columns); columnIndex++){       
      if (columns[columnName].justify == "left") {       
       headerLabels &= LJustify(columns[columnName].label, columns[columnName].length) & " "; 
      } else {      
       headerLabels &= RJustify(columns[columnName].label, columns[columnName].length) & " "; 
      } 
      headerUnderlines &= RepeatString("-", columns[columnName].length) & " "; 
     }  
     reportHeaders = headerLabels & variables.newLine & headerUnderlines; 

    </cfscript> 

eqInventoryHelper.cfc：

<cffunction name="getPreformattedColumnCharacteristics" output="false"> 
    <cfargument name="showComponents" required="true"/> 
    <cfscript> 
     var columnSort = 1;

      useful_life = {label = "Useful Life", length = 12, justify = "right", sortOrder = columnSort++} 
     }; 

     // If showing components, we tack the component specific columns to the main columns array. 
     if (arguments.showComponents) { 
      columns.component_num = {label = "Component Number", length = 18, justify = "left", sortOrder = columnSort++}; 
      columns.component_desc = {label = "Component Description", length = 45, justify = "left", sortOrder = columnSort++}; 
      columns.component_manufacturer_name = {label = "Manufacturer Name", length = 18, justify = "left", sortOrder = columnSort++}; 
      columns.component_model_num = {label = "Manufacturer Model Number", length = 26, justify = "left", sortOrder = columnSort++}; 
      columns.component_serial_num = {label = "Serial Number", length = 20, justify = "left", sortOrder = columnSort++}; 
      columns.component_po_number = {label = "PO Number", length = 12, justify = "right", sortOrder = columnSort++}; 
     } 
     return columns; 
    </cfscript> 
</cffunction> 

謝謝。

我強烈懷疑您使用的是早於for(index in array)語法的ColdFusion版本。 This was only added in ColdFusion 9.0.1。

所以，如果你正在運行9.0，它不會工作，它會假設你的意思是迭代結構。
