> Setting a RadioButton with export values does not update the appearance. The
> attached form has two sets of RadioButtons. One called "Group1" and one
> called "\_6_ Treatment of Program Inco_nwAbuWIn0JWsW9e68RWN8A". "Group1" is
> easy to set or unset. I noticed during debugging doesn't have any
> "ExportValues" and so the value is set in a different way than the other set
> of RadioButtons. "\_6_ Treatment of Program Inco_nwAbuWIn0JWsW9e68RWN8A"
> does have ExportValues and this appears to be related to the problems with
> setting the value.
> For example:
> {code}
> try(PDDocument pdfDocument = PDDocument.load(new
> File("/Users/travis/Desktop/fdpAttachment2.pdf"))) {
> final PDDocumentCatalog docCatalog =
> pdfDocument.getDocumentCatalog();
> final PDAcroForm acroForm = docCatalog.getAcroForm();
> final PDRadioButton group1Field = (PDRadioButton)
> acroForm.getField("Group1");
> group1Field.setValue("NIH");
> final PDRadioButton topiField = (PDRadioButton)
> acroForm.getField("_6_ Treatment of Program Inco_nwAbuWIn0JWsW9e68RWN8A");
> topiField.setValue("Additive");
>
> pdfDocument.save("/Users/travis/Desktop/fdpAttachment2-radio-buttons.pdf");
> }
> {code}
> Notice in "fdpAttachment2-radio-buttons.pdf" that "Group1" RadioButton has
> NIH toggled while "\_6_ Treatment of Program Inco_nwAbuWIn0JWsW9e68RWN8A" is
> not toggled even though "Additive" is a valid value.
> The workaround for this is to set the appearance state (AS). I'm still
> learning the pdfbox api so I apologize if my workaround is a little strange.
> {code}
> try(PDDocument pdfDocument = PDDocument.load(new
> File("/Users/travis/Desktop/fdpAttachment2.pdf"))) {
> final PDDocumentCatalog docCatalog =
> pdfDocument.getDocumentCatalog();
> final PDAcroForm acroForm = docCatalog.getAcroForm();
> final PDRadioButton group1Field = (PDRadioButton)
> acroForm.getField("Group1");
> group1Field.setValue("NIH");
> final PDRadioButton topiField = (PDRadioButton)
> acroForm.getField("_6_ Treatment of Program Inco_nwAbuWIn0JWsW9e68RWN8A");
> topiField.setValue("Additive");
> //Additive ends up being index 0. If I add an AS with "0" it
> toggle the Additive radio button
> final int idx =
> topiField.getExportValues().indexOf((topiField).getValue());
> topiField.getWidgets().forEach(w -> {
> PDAppearanceEntry appearanceEntry =
> w.getAppearance().getNormalAppearance();
> if (((COSDictionary)
> appearanceEntry.getCOSObject()).containsKey(String.valueOf(idx))) {
> w.getCOSObject().setName(COSName.AS, String.valueOf(idx));
> }
> });
>
> pdfDocument.save("/Users/travis/Desktop/fdpAttachment2-radio-buttons-workaround.pdf");
> }
> {code}
> Notice in "fdpAttachment2-radio-buttons-workaround.pdf" both sets of
> RadioButtons are toggled which is the desired behavior
