Tilman Hausherr updated PDFBOX-5225:

Description: 
{code}
PDAcroForm acroForm = doc.getDocumentCatalog().getAcroForm();
List 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.

  was:
{code}
PDAcroForm acroForm = doc.getDocumentCatalog().getAcroForm();
List 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.
