Hi Paolo,
thanks for your effort.
I'm not sure you know that cartoon with the stork that has almost completely
swallowed the frog, but the frog is still gagging the storks throat and caption
says 'Never give up'.
I have used the pdf toolbox to inspect my 2ndpage.pdf. It seems to me that on
the (empty) first page there are some remainders (streams) of the flattened
form, namely the filled in fields. Why this isn't visible is beyond me. What
used to be the static text of the form seems to be gone.
How could such a thing happen?
I'm rechecking my code, but I cannot see how I could inadvertently step on
content that I have already added to a document.

An: Post all your questions about iText here
Betreff: Re: [iText-questions] Is a flattened form special?
I can't reproduce the problem. I did:
PdfReader r = new PdfReader("c:\\hihi.pdf");
Image img = Image.getInstance(writer.getImportedPage(r, 1));
img.setAbsolutePosition(0, 0);
doc.add(img);
doc.newPage();
in all the files that you sent and all worked correctly. It may be some freak
problem from a faulty JVM instalation, I don't know.
