Coldfusion struct array错误

Question

我正在尝试构建数组以存储报告列名，但是我收到以下错误：您试图取消引用类coldfusion.runtime类型的标量变量。数组作为具有成员的结构。

我的代码是：

<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;

            ucop_tag_num = {label = "UCOP Tag Number", length = 16, justify = "left", sortOrder = columnSort++},

            asset_type = {label = "Asset Type", length = 11, justify = "left", sortOrder = columnSort++},
            is_uc_title = {label = "UCD Title", length = 14, justify = "left", sortOrder = columnSort++},

            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>

谢谢。

我强烈怀疑您使用的是一种早于for(index in array)语法的ColdFusion版本。 This was only added in ColdFusion 9.0.1

因此，如果您运行9.0，它将无法工作，并且它将假定您要迭代结构。
