Coldfusion：获取NullPointerException尝试编辑电子表格
我有一个模板电子表格我想编辑，所以我可以插入数据到它。
然而，这个代码显然应该只是抛出一个NullPointerException。 错误总是出现在代码的“写入”部分。 电子表格读取正常。
<!--- Read spreadsheet ---> <cfspreadsheet action="read" src="#theFileCopy#" name="sObj" /> <!--- Set cell value ---> <cfset spreadsheetSetCellValue(sObj, "Test", 3, 3)> <!--- Write spreadsheet ---> <cfspreadsheet action="write" overwrite="true" filename="#theFileCopy#" name="sObj" /> 堆栈跟踪：

问题是该文件是xlsx格式。 出于某种原因，Coldfusion将以xslx的方式读取，但不会将其写回。 文档确实说电子表格行动=只写xls。 想知道这样做的任何方法。
