我创建了一个包含两个表单字段的快速 PDF 文件,名字和姓氏(或名字和姓氏),带有提交按钮,并使用以下代码尝试在新的 PDF 文件中填充这些字段:
<cfpdfform action="populate" source="#variables.AbsPath#\test.pdf">
<cfpdfformparam name="FirstName" value="foo" />
<cfpdfformparam name="LastName" value="bar" />
</cfpdfform>
但是,我收到此错误:
The system has attempted to use an undefined value, which usually indicates a programming error, either in your code or some system code.
Null Pointers are another name for undefined values.
Platform, Locale, and Platform Name must not be null
我尝试阅读 PDF 文件以确保使用此表单字段是正确的,它们是:
<cfpdfform action="read" source="#variables.AbsPath#\test.pdf" result="fields" />
<cfdump var="#fields#">
结构转储:
FirstName: [empty string]
LastName: [empty string]
Submit: [empty string]
我尝试搜索 Adobe 文档和其他一些站点,但找不到此错误的解决方案。我还尝试在 cfpdfform 标记中添加一个“destination”参数以防万一,但得到了相同的结果。PDF 文件确实存在。有任何想法吗?提前致谢。
更新:这是堆栈跟踪:
