------------------------------------
Attachment: test2.pdf
Sample file demonstrating the issue (compare Group1 and Group2).
Code:
PDDocument doc = PDDocument.load( new File("test2.pdf") );
PDAcroForm form = doc.getDocumentCatalog().getAcroForm();
List<PDField> fields = form.getFields();
for (PDField f: fields) {
System.out.println("Name:" + f.getFullyQualifiedName());
System.out.println("Type:" + f.getFieldType());
System.out.println("Class:" + f.getClass());
List<COSObjectable> kids = f.getKids();
if (kids!=null) {
for (COSObjectable c : kids)
{ System.out.println("Kid Class: " + c.getClass()); }
}
}

> (Continuation of https://issues.apache.org/jira/browse/PDFBOX-2617)
> A group of radio-buttons is an object of the PDRadioCollection class and each
> child of that group is an PDCheckbox object.
> However, if the group only contains one widget the getKids method of the
> PDRadioCollection object returns null.
> There should be at least one child for any such group.
