Description

It is impossible to set the upper radio button with this code, the lower is set. With "2" also.

String filename = "..../AU_Erklaerung_finalAB.pdf";
PDDocument pdfDocument = Loader.loadPDF(new File(filename));
PDAcroForm acroForm = pdfDocument.getDocumentCatalog().getAcroForm();
acroForm.getField("Formular1[0].Seite1[0].TF_P[0].Optionsfeldliste[0]").setValue("1");
pdfDocument.save(filename + System.currentTimeMillis() + ".pdf");

Attached: the original file from the user, plus two files where it was set with Adobe Reader.

What really happens:

The values from the /Opt entry are 1 and 2, the values at the dictionary level are 0 and 1. Our software somehow gets confused when 1 is used because it appears in both: when the value "1" is set, then PDButton.updateByOption() is called twice (!!!), once with value 1 and once with 2.

The same effect happens with setValue(0) (integer parameter) if we cast the field to a PDRadioButton.

I changed the PDF so that the /Opt entry has "A" and "B" instead of "1" and "2" and then it works. (However that can't be changed with Adobe Reader)

The Adobe filled files have 0 and 1 as /V value, we set 1 and 2 as /V value.
