PDFBOX acroForm填充，但当在Acrobat阅读器中打开时，值消失

Question

我有PDF表单，我正在尝试用PDFBOX填充它。它可以工作，表单被填充，我用其他阅读器或浏览器打开，我可以看到值，但是当我试图在Adobe Reader中打开值消失时，我尝试了各种可能的方法来找出原因但是值不可见。

我有模板表单，我使用和填充数据，重命名字段，并将其合并到其他文档中，然后重做该过程，直到所有表单都填满。

我不确定这是否与我的代码或Adobe阅读器有关。

数据类定义

data class DiversionData(

    val fuelType: String,

    val shipperTaxPayerNumber: String,
    val quantity: Double,
    val originalDestination: String,
    val revisedDestination: String,
    val importNumber: String?,
    val date: LocalDate,
    val billOfLading: String,
)

Answer 1

页面/AA/O条目（“打开页面时应执行的操作”）包含以下内容：

if (!bReset)
{
    this.resetForm();
    bReset = true;
}

所以表单被重置。

即使手动填写表单并保存、关闭和重新打开，也会发生这种情况。也许这是“formupack”的一个演示版，它是故意这么做的。

您可以通过如下方式删除page/AA条目来防止这种情况

document.getPage(0).setActions(null);

或者删除/O条目

document.getPage(0).getActions().setO(null);
