Summary: Adding a signature on nested fields has no effect
Key: PDFBOX-5344
URL: https://issues.apache.org/jira/browse/PDFBOX-5344
Project: PDFBox
Issue Type: Bug
Components: Signing
Affects Versions: 2.0.24
Reporter: Laurence Urbain
Attachments: nested-signature-field.pdf
Hi,
I am not to sign a document if the signature field is nested (the signature
field is not a direct child of the acro form).
When I call the method PDDocument.addSignature(), the signature field is
properly marked as "needs to be updated" but not its parents.
As a result, when the incremental save is done, the changes are lost.
To be able to add the signature for such field, all the parent fields in the
hierachy should also be marked as "needs to be updated".
Please find a sample file attached.
Here is the code snippet to build it:
{code:java}
final PDDocument pdDocument = new PDDocument();
final PDPage page = new PDPage();
pdDocument.addPage(page);
PDAcroForm form = new PDAcroForm(pdDocument);
pdDocument.getDocumentCatalog().setAcroForm(form);
final PDNonTerminalField level1 = new PDNonTerminalField(form);
level1.setPartialName("level1");
form.getFields().add(level1);
final PDNonTerminalField level2 = new PDNonTerminalField(form);
level2.setPartialName("level2");
level1.setChildren(List.of(level2));
final PDSignatureField signatureField = new PDSignatureField(form);
signatureField.setPartialName("field1");
PDAnnotationWidget widget = signatureField.getWidgets().get(0);
widget.setRectangle(new PDRectangle(50, 700, 200, 20));
widget.setPage(page);
widget.setPrinted(true);
page.getAnnotations().add(widget);
level2.setChildren(List.of(signatureField)); {code}
Thanks
