<font size="2">Hello,
<br><br>I'm working with the itext 2.0.4 library in a Java Project in
Colombia. I've checked out the documentation (FAQ and mailing list) and
I don't found any documentation arround this issue I'm having.
<br><br>The problem is that I'm getting a ClassCastException when closing a
stamper in my project. Here is the stacktrace
<br><br>java.lang.ClassCastException: com.lowagie.text.pdf.PdfNull incompatible
with com.lowagie.text.pdf.PdfDictionary
<br>&nbsp;&nbsp;&nbsp; at com.lowagie.text.pdf.PdfStamperImp.flatFields(Unknown
<br>&nbsp;&nbsp;&nbsp; at com.lowagie.text.pdf.PdfStamperImp.close(Unknown
<br>&nbsp;&nbsp;&nbsp; at com.lowagie.text.pdf.PdfStamper.close(Unknown Source)
<br><br>Here is a fragment of my code.
reader = new PdfReader("test.pdf");
<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; stamper
= new PdfStamper(reader, new FileOutputStream("test2.pdf");
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;
AcroFields form = stamper.getAcroFields();
<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; form
.setField("adendo_numdijin", "test3");
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; form
.setField("adendo_numero", "test4");
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .....
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; stamper
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; stamper
<br><br>As I mentioned before, the exception arrives when the close
method is called.&nbsp; It is a rare issue, because i have similiar form and
the library works really great...
<br><br>If i erase the&nbsp;&nbsp; stamper.setFormFlattening(true); line the
program runs fine, but it leaves the document as a form.
<br><br>Can somebody help with this issue
