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.
