Concatenation issue

Pdf concatenation works with several data flaws even though files are flattened. The output I get isn’t exact combined copy of those 3 files (first page almost fine except page number, but second and third pages get the invoice number and order information from the first page). Is there a different way to merge pdf flattened xfa forms into one pdf file without making any change to their content?

Would you please share source and generated files along with a narrowed down code snippet reproducing the problem so that we may try to reproduce and investigate it in our environment. Before sharing requested data, please ensure using latest version of the API.

PdfFileEditor pdfEditor = new PdfFileEditor();

FileStream outputStream = new FileStream(Path.Combine(TEMP_DIR, "temp_stream.pdf"), FileMode.Create);

FileStream[] inputStreams = new FileStream[filesFromDirectory.Count()];

//Merge streams

for (int i = 0; i < filesFromDirectory.Count(); i++)

{

inputStreams[i] = new FileStream(filesFromDirectory[i], FileMode.Open);

}

//Create output form streams

pdfEditor.Concatenate(inputStreams, outputStream);
