That would be the difference between "static" and "dynamic" XFA forms. Static forms have all the PDF infrastructure already in place, and iText can work with that (mostly). Dynamic forms have no PDF fields matching the ones defined in their XFA... iText has no idea how to render them, so such forms remain blank. How do you tell the difference? Hmm... There's no such function in the XfaForm object... Here's a plan. Check the first few pages for annotations or page content. If they lack both, it's a dynamic XFA form. If it has them, it's (probably) a static form. If you know there's a field named X, you can query the AcroForm for that field's merged dictionary (or widget, or whatever). If it cannot find it, it's dynamic. --Mark Storer Senior Software Engineer Cardiff.com import legalese.Disclaimer; Disclaimer<Cardiff> DisCard = null; > -----Original Message----- > From: Craig Garvis [mailto:[email protected]] > Sent: Tuesday, August 17, 2010 5:21 PM > To: Post all your questions about iText here > Subject: Re: [iText-questions] iText Flattening causing data > loss/distortion? > > Thanks Mark, > > I am flattening forms before I attempt to merge them into the > combined document.
