Ernst Eibensteiner commented on PDFBOX-1100:
--------------------------------------------
obviously the COSDictionary does not contain the correct value:
PDDocument pdf = PDDocument.load("C:\\tmp\\a.pdf");
PDDocumentCatalog docCatalog = pdf.getDocumentCatalog();
PDAcroForm acroForm = docCatalog.getAcroForm();
System.out.println("acroForm COSObject:
"+acroForm.getCOSObject().toString());
List<PDField> list = acroForm.getFields();
Iterator<PDField> it = list.iterator();
while (it.hasNext()) {
PDField field = it.next();
System.out.println("fieldCOSObject:
"+field.getCOSObject().toString());
}
Output shows:
acroForm COSObject: ..... COSName{Fields}:COSArray{[COSObject{31, 0},
COSObject{32, 0}]})
correct COSObject 31 and 32 found for the Fields!
but
COSObject 31 does not contain COSName{V}
COSObject 32 does not contain COSName{V}
if I open the same document using http://www.pdftron.com/ I can see the correct
COSName{V} for both COSObjects (Object number 31 and 32) containing the correct
value.

> Merging two PDFs with form fields results in a PDF with empty fields.
> The issue seems to be similar to
> https://issues.apache.org/jira/browse/PDFBOX-1031, but in my case i see the

> c.pdf
