So what did you mean in your earlier mail, quoted below, when you said "It _IS_
possible to fill in a PDF that has been "Reader
Enabled" w/o violating the rights"?

It can't.
If you make ANY changes to the PDF you will break the rights. It's specifically
designed this way to detect tampering.
The only choice you have, if you wish to distribute a file with Reader
Enablement is to purchase Adobe LiveCycle ES and have it
process your document AFTER you do whatever dynamic functionality you wish.

I don't get it. How should this code be rewritten so that the resulting PDF
still has the rights? Do you know for a fact that it can
be done?

You rewrote the PDF - therefore you changed it.

Leonard,
Are you sure? I have tried a few variations and I have not been able to get
anything to work. I now have a simple identity() routine
that changes nothing. The incoming PDF has rights that lets Reader save
filled-in data. The resulting PDF has the rights removed. As
far as I can tell, I changed nothing. What did I do wrong? Here is the code:
public static void identity()
{
PdfReader reader = new PdfReader("C:/tmp/niceForm.pdf");
reader.setAppendable(true);
XfaForm xfaForm = new XfaForm(reader);
FileOutputStream pdfOutput = new FileOutputStream("C:/tmp/newFormOut.pdf");
PdfStamper stamper = new PdfStamper(reader, pdfOutput);
xfaForm.setXfa(stamper.getWriter());
stamper.close();
pdfOutput.close();
reader.close();
}

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?
