Maruan Sahyoun commented on PDFBOX-2617:
----------------------------------------
A small clarification. The reporter wrote that for a PDRadioCollection object
the kids were returned as PDCheckbox object. This behavior was wrong and has
changed with the fix but only for 2.0.0 to not break current 1.8 dependent code.
> Group of Button fields treated as a Radio Button group

> When creating a group of identical button fields PDFBox reads them as a group
> of radio-button fields, with each widget as a check-box, which is incorrect.
> The main field has the class PDRadioCollection and each kid is a PDCheckbox.
> Run the following code on the attached file:
> PDDocument doc = PDDocument.load( new File("test.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());
>
> }
>
> }
> }
> The results are:
> Name:Test
> Type:Btn
> Class:class org.apache.pdfbox.pdmodel.interactive.form.PDRadioCollection
> Kid Class: class org.apache.pdfbox.pdmodel.interactive.form.PDCheckbox
> Kid Class: class org.apache.pdfbox.pdmodel.interactive.form.PDCheckbox
