Hi,
The pages have only the widget annotations. The form fields are related
to the document catalog. Each field has one or more widgets. So it's
more tricky. The best would be to create a copy of the document and then
delete pages.

Hello all, newb here;
I have a source PDF file, and I need to build a new file from it by selectively
copying/not copying/duplicating pages, and filling out annotated fields in the
new file. Eg. sometimes the new file will have 6 pages, sometimes it will have
10 pages.
So far, my searches haven't turned up people asking questions about quite this
situation:
1. one or more of the pages are forms, eg. have annotated fields and need to
fill them in.
2. one of the form pages needs to get repeated in certain circumstances - mine
is a table-of-inputs page with a header. May need zero, may need 1 or more
copies filled out.
I don't have a deep understanding of how the PDFBox operates, so I tried my
simplistic version from the Javadocs and some Google-fu:
pddoc.importPage(originalDoc.getPage(0));
cat = pddoc.getDocumentCatalog();
acroForm = cat.getAcroForm();// returns null
field = acroForm.getField("name");// blows up with an NPE
Meaning there is no PDAcroForm in the new PDDocument after I copy the first
page, which has form fields. At least no cached version, according to my
debugger. How do I get it to generate an appropriate AcroForm? Or do I need
to wait for an AcroForm until all pages, or at least all field-containing
pages, are in my pddoc before doing that?
My secondary question addresses #2 above: how can I have 2 copies of the same
page (form), and annotated elements, in one PDDocument? Does the 2nd copy of
the PDPage need to rename all fields so all annotation names remain unique? Or
can I operate on a copy of the PDPage and then import it into the final pddoc
(assuming once the page has values, names won't interfere with existing names
in the same PDDocument)?
Websites, example code, deeper knowledge all appreciated!
P.S. and thanks to daedtech.com for getting me started!
