Hi Maruan,
I made this minor change to retrieve the NormalAppearance, and it worked.
Thanks for basically providing the solution.
PDRadioCollection radioCollection = (PDRadioCollection) field;
PDCheckbox onCheckbox = (PDCheckbox)
radioCollection.getKids().get(1);
PDAppearanceDictionary apDictionary =
onCheckbox.getWidget().getAppearance();
// get the fields normal appearances i.e. the options to be
selected
Map<String,PDAppearanceStream> normalAppearances =
apDictionary.getNormalAppearance();

Thanks Maruan!
However, when try to use the code, I get an exception in line 4th line:
Exception in thread "main" java.lang.ClassCastException:
org.apache.pdfbox.pdmodel.interactive.form.PDCheckbox cannot be cast to
org.apache.pdfbox.pdmodel.interactive.annotation.PDAnnotationWidget
As a reminder, I'm using PDFBox 1.8.8 if that matters. In the meantime, I'll
play around with what you provided and see if I can get it to work.

Hi,
here you go.
PDDocument document = PDDocument.load("form_b122a-2.pdf");
PDAcroForm form = document.getDocumentCatalog().getAcroForm();
PDField field = form.getField("CheckBox16");
PDAnnotationWidget widget = (PDAnnotationWidget)
field.getKids().get(1);
// get the fields normal appearances i.e. the options to be
selected
Map<String,PDAppearanceStream> normalAppearances =
widget.getAppearance().getNormalAppearance();
// Print out the current entries. There are two options
// On and Off
System.out.println(normalAppearances);
// Add a new entry with the desired value copying over the
// appearance stream of the to be 'renamed' entry
normalAppearances.put("Yes",normalAppearances.get("On"));
normalAppearances.remove("On");
// Print out the new entries. There are two options
// Yes and Off
System.out.println(normalAppearances);
document.save("form_b122a-2-pdfbox.pdf");
document.close();
BR
