Hi Tilman,
thanks a lot for the analysis!
So I am assuming correct that you will raise a bug ticket?
https://issues.apache.org/jira/browse/PDFBOX-5831
I'll wait a day or two because I'm not the acroform guy, and then I'll
fix it myself.
I am not the creator of this PDF. We have to deal with the official PDFs
provided by the government institution that you mentioned. More PDFs can be
found here:https://www.bundesfreiwilligendienst.de/service/downloads
Hope that they haven’t more that fishy PDFs published.
I changed the PDF so that the /Opt entry has "A" and "B" instead of "1" and "2"
and then it works.
For my knowledge in the meantime for a potential workaround: how did you do
that?
I edited the PDF with NOTEPAD++. But it should also be able this way:
field.setExportValues(List.of("A", "B"));
the field must be cast to a PDRadioButton. However I noticed that after
doing this change, I was no longer able to edit it with Adobe Reader.
Another problem is that I get a sort of error message:
This might be because of UR3 usage rights signature.
Tilman
Best regards
Martin

I'll have another look tomorrow when I'm more awake. I just looked and it happens like you wrote. I
traced through the code and it seemed to work properly, i.e. going through different paths for
"1" and "2" (looking for dictionary elements 0 and 1) but the result was always
the same which contradicts the observation, but that is the fascination in debugging.
I had another look. 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.
I changed the PDF so that the /Opt entry has "A" and "B" instead of "1" and "2"
and then it works.
So I'd say it's a PDFBox bug. The good thing is that the copyright of that PDF
would be with a government institution (BAFzA) so we can use it as a test.
Are you the creator of that PDF?
