             Summary: Casting error for PDRadioButton when trying to exportFDF
                 Key: PDFBOX-2761
                 URL: https://issues.apache.org/jira/browse/PDFBOX-2761
             Project: PDFBox
          Issue Type: Bug
          Components: AcroForm
    Affects Versions: 2.0.0
            Reporter: Jason Mackin


When trying to exportFDF() in PDAcroForm.java, there is a ClassCastException thrown when addFieldAndChilden(PDFieldTreeNode docField, List<FDFField> fdfFields) is called and the docField is a PDRadioButton that has kids and one is a PDWidget.

PDRadioButton.getKids() says:
"This will get all the kids of this field. The values in the list will either be PDWidget or PDField. Normally they will be PDWidget objects unless this is a non-terminal field and they will be child PDField objects."

But when kids are returned in the addFieldAndChilden method and one is a PDWidget (PDAnnotationWidget in my case), it tries to cast it as a PDFieldTreeNode and throws the exception.
