How to merge dynamic PDFs?

Aspose-Pdf-9.3.0 for Java

I am attempting to merge the contents of 2 PDF files. These PDFs were created using Adobe Lifecycle designer and contain dynamic forms, and so have been saved as a Dynamic PDFs.

Using the following code taken from your example:

com.aspose.pdf.Document pdfDocument1 = new com.aspose.pdf.Document(myDir + "someDoc1.pdf");

com.aspose.pdf.Document pdfDocument2 = new com.aspose.pdf.Document(myDir + "someDoc2.pdf");

com.aspose.pdf.Document pdfDocument3 = new com.aspose.pdf.Document();

pdfDocument3.getPages().add(pdfDocument1.getPages());

pdfDocument3.getPages().add(pdfDocument2.getPages());

pdfDocument3.save(myDir + "Merged.pdf");

pdfDocument3.dispose();

I can successfully merge the contents of two Static PDFs containing Forms, but this does not work as soon as you try to use a PDF that includes a Dynamic Form. If using a Dynamic form and trying to view the merged PDF in Adobe Reader, you will only ever see this message: "If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document."

Is this just a limitation of the toolkit? Should I be / is there a way to convert the Dynamic PDFs to a Static representation before I attempt this merge? I am attaching a sample Dynamic PDF for reference. Thank You.
