I would say that this is because Adobe Reader renders the form from the
PDF and LiveCycle renders from the XDP template section. I have always
treated the XDP template section as read-only. I don't think this is
the way to do what you want.
Is there some JavaScript that would work to do what you want? In some
code I've done we enable and disable buttons based on some business logic.

Hi ,
I want to hidden a button in the pdf form, I get DomDocuement by
XfaForm getDomDocument(), and I traversal the docuement, get the
button field and add "presence" attribute, but the button not be hidden.
source:
PdfReader reader = new PdfReader("c:\\pdfform.pdf");
FileOutputStream out = new FileOutputStream("c:\\newpdfform.pdf");
PdfStamper stamper = new PdfStamper(reader, out);
XfaForm form = new XfaForm(reader);
org.w3c.dom.Node templateNode = form.getDomDocument().getFirstChild();
//travsal to get button field
.....
//set button node to fieldNode
org.w3c.dom.Node presenceAttr = fieldNode.getAttributes()
.getNamedItem("presence");
if ("true".equalsIgnoreCase(value)) {
// show this field
if (presenceAttr != null) {
presenceAttr.setNodeValue("visible");
}
} else if ("false".equalsIgnoreCase(value)) {
// hidden this field
if (presenceAttr != null) {
presenceAttr.setNodeValue ("hidden");
} else {
org.w3c.dom.Element ele = (Element) fieldNode
.cloneNode(true);
ele.setAttribute("presence", "hidden");
org.w3c.dom.Node parentNode = fieldNode
.getParentNode();
parentNode.replaceChild(ele, fieldNode);
}
}
PdfWriter writer = stamper.getWriter();
form.setXfa(writer);
stamper.close();
reader();
when I open "newpdfform.pdf", I find the button not be hidden, but if
I open this file in lifecycle designer and this button field is hidden
in the pdf preview.
how should I do to hidden this button?
