问题
I have PDF form, I am trying to fill it with PDFBOX. It works, form is filled and I open with other reader or browser, I can see values, however When I tries to open in Adobe Reader values disappears, I tried every possible way to find out why But values, are not visible.
I have template form, that I use and fill data, rename fields, and merge it into other document, and redo that process until all forms are filled up.
I am not sure if this related to my code or Adobe reader.
Link to PDF form I need to fill
here is my code to populate form.

val form = sourceDocument.documentCatalog.acroForm
fillHeader(form, headerParam, totalPages, totalPages, data)
fillData(form, data, totalPages)
return sourceDocument
} else {
val resultDocument = PDDocument()
chunks.forEachIndexed { currentPage, it ->
val sourceDocument = getTemplate(templatePath)

fillHeader(form, headerParam, currentPage, totalPages, it)

回答1:
The page /AA/O entry ("An action that shall be performed when the page is opened") has this:
if (!bReset)
{
this.resetForm();
bReset = true;
}
So the form is reset.
This happens even if the form is filled manually and saved, closed and reopened. Maybe this is a demo version of "formupack" that does this on purpose.
You could prevent this by removing the page /AA entry like this
document.getPage(0).setActions(null);
or just remove the /O entry
document.getPage(0).getActions().setO(null);
