Tilman Hausherr commented on PDFBOX-5225:
-----------------------------------------
My thought was to change the second part of that method to this:
{code}
Set<COSDictionary> widgetDictionarySet = new HashSet<>();
for (PDField field : fields)
{
List<PDAnnotationWidget> widgets = field.getWidgets();
for (PDAnnotationWidget widget : widgets)
{
widgetDictionarySet.add(widget.getCOSObject());
}
}
for (PDPage page : document.getPages())
{
for (PDAnnotation annotation : page.getAnnotations())
{
if (widgetDictionarySet.contains(annotation.getCOSObject()))
{
fillPagesAnnotationMap(pagesAnnotationsMap, page,
(PDAnnotationWidget) annotation);
}
}
}
{code}
It seems to work but now the annotations are direct objects, and the file can't
be opened with Adobe Reader.
> Flattening removes all annotations when widget annotation has no page

> Project: PDFBox
> Issue Type: Bug
> Components: AcroForm
> Affects Versions: 2.0.24
> Reporter: Tilman Hausherr
> Priority: Major
> Attachments: SourceFailure.pdf
>
>
> {code}
> PDAcroForm acroForm = doc.getDocumentCatalog().getAcroForm();
> List<PDField> list = new ArrayList<>();
> list.add(acroForm.getField("VN_NAME"));
> acroForm.flatten(list, true);
> {code}
> The code from buildPagesWidgetsMap that is run when there are widgets with
> missing page references does not consider the field list. So all widgets end
> up in the map instead of only those we care about.
