Tilman Hausherr created PDFBOX-5831:
---------------------------------------
Summary: Radio button can't be set
Key: PDFBOX-5831
URL: https://issues.apache.org/jira/browse/PDFBOX-5831
Project: PDFBox
Issue Type: Bug
Components: AcroForm
Affects Versions: 3.0.2 PDFBox
Reporter: Tilman Hausherr
Attachments: AU_Erklaerung_final-lower.pdf,
AU_Erklaerung_final-upper.pdf, AU_Erklaerung_final.pdf
It is impossible to set the upper radio button with this code, the lower is
set. With "2" also.
{code:java}
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");
{code}
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)}} 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.
