"The PDF was authored so that it can be opened in Adobe Reader, fields

file system."
I feel like I'm missing something. You've got a PDF that appears to
have at least PdfWriter.ALLOW_FILL_IN. If the form has that permission
(retrieved from PdfReader.getPermissions()) then your code should allow
you to fill in the form. If it has other permissions too then just set
the output PDF with the result of PdfReader.getPermissions() using the
PdfEncryptor. Something on the order of:
PdfReader reader = new PdfReader( "input.pdf" );
int pdfPermissions = reader.getPermissions();
if( !(pdfPermissions & PdfWriter.ALLOW_FILL_IN))
// throw exception? exit? either way, don't allow the form to be
filled
//
// modify the pdf contents as needed
//
PdfEncryptor.encrypt( reader,
new FileOutputStream( "output.pdf"),
null, null, // no user name and password
pdfPermissions,
true);
I apologize if I've missed something but it seems that, based on your
original question, this is what you wanted.

Leonard,
Is there any documentation anywhere on this? Do you know of an
example iText program that I could look at?

the rights
It _IS_ possible to fill in a PDF that has been "Reader Enabled"
w/o violating the rights - but it MUST be done in a very specific
fashion using "append mode" on the source PDF AND only modifying
a limited number of objects in the PDF.
So yes, if you are going to create a whole new PDF - you'll break
the "Reader Enabling". If you're careful about what you do, and
how you do it, you CAN accomplish your goal.

I have a PDF containing an XFA form; isXfaPresent() == true.
The PDF was authored so that it can be opened in Adobe Reader,
fields in the form can be filled, and the form can be saved by
Reader to the file system.
Using iText I have read in the PDF, obtained the XfaForm,
changed values in the XML Document, and written a new PDF to the
file system.
The PDF I write out contains the values I put into the XML, but
the rights to save the PDF from Reader have been lost. Is this
expected? Other features of the original PDF are also lost in
the newly-written PDF.
I wrote the changed PDF to a new file. If this is the reason
the save rights were lost, is there a way I can modify the
existing PDF in place so that the rights to save the file from
Adobe Reader are maintained?
