Thank you, Thank you, Thank you. The second suggestion was exactly what i was looking for.
For those who are reading this also, you can use "Not the correct syntax" -- AcroField.renameField(String oldName, String newName) to rename the field. >From: "Mark Storer" <[EMAIL PROTECTED]> >Reply-To: Post all your questions about iText here ><[email protected]> >To: "Post all your questions about iText here" ><[email protected]> >Subject: Re: [iText-questions] AcroForm and AcroField PLUS FAQ ENTRY >Date: Thu, 31 Aug 2006 12:35:53 -0700 > >I'm pretty sure this is in the FAQ somewhere.
