Hi,
my recent works could help. I have been trying using the iText
acroFields.mergeXfaData(...), but I faced a bug with duplicated subforms
assigned to different datas (same structure)...
That seems to happen because of a corrupted mapping between short and long
names in AcroFieldSearch class... I tried to fix it, but I lost myself in
the depth of code ;-) !
So, I did it my own way, merging XFA dataset with a classic XML merging
approach... sounds trivial, but works fine.
Here is my code, if that can help (form is an instance of an home-made class
defining a set of pdf form, datas to merge aso...):
PdfReader pdfReader = new PdfReader(form.getFormTemplate().getURI());
XfaForm xfaForm = new XfaForm(pdfReader);
if (!xfaForm.isXfaPresent()) {
form.setState(IForm.STATE_FAILED);
throw new Exception("Not an XFA Form !!");
}
FileOutputStream pdfOutputStream = new
FileOutputStream(form.getMergedPath());
PdfStamper pdfStamper = new PdfStamper(pdfReader, pdfOutputStream);
Document dataSetDocument =
XmlDomHelper.loadDomDocument(form.getDataFlow().getURI());
Node dataSetsNode =
XPathAPI.selectSingleNode(dataSetDocument.getDocumentElement(),
"//xfa:data", dataSetDocument);
// Get data definitions from xfa structure (link to an xfa form file through
form instance)
Document xfaDocument = xfaForm.getDomDocument();
Node newXfaDataSetsNode =
xfaDocument.importNode(dataSetsNode.cloneNode(true), true);
Node xfaDataSetsNode =
XPathAPI.selectSingleNode(xfaDocument.getDocumentElement(), "//xfa:data",
dataSetDocument);
// Replacement of the dataset definition in xfa-form with the filled dataset
from the xml business datas:
xfaDataSetsNode.getParentNode().replaceChild(newXfaDataSetsNode,
xfaDataSetsNode);
xfaForm.setDomDocument(xfaDocument);
xfaForm.setChanged(true);
XfaForm.setXfa(XfaForm.serializeDoc(xfaForm.getDomDocument()),
pdfStamper.getReader(), pdfStamper.getWriter());
pdfStamper.close();
pdfReader.close();
form.setState(IForm.STATE_MERGED);
