> 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
> Attachments: az101-1.15.0_withholding-form-info.json
>
>
> 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.
