XFA PDF concatenation

[GuiPATRY]

I have a PDF that open fine in Adobe, but when added (concatenated) into a document we have a simple page that contains the message "please wait" indicating that the viewer can not manipulate the PDF.

Opening the PDF in chrome gives the same result (ie a page with the same message). In Firefox we have a set of fields that are empty, and no other values.

Internet searches indicate that this may be XFA PDF.

Is there a way to concatenate those PDF with the correct result ?

Thanks in advance
Guillaume

Hello,

Thanks for your inquiry.

I have reproduced the issue you encountered with your "PDF Problem 1.PDF" pdf file and have logged it into our issue system with the tracking number SPIREPDF-7967.
We apologize for any inconvenience caused and will keep you updated on the progress of the issue.

Is there any new on a correction ?
or a way to detect the fact that is is an XFA so that we can emit a warning ?

Hello,

Thank you for your inquiry.
We apologize that the issue SPIREPDF-7967 has not been resolved yet. You can use the following code to check if the current PDF contains XFA fields.

Code: Select all

PdfDocument doc = new PdfDocument();
doc.LoadFromFile(pdfs[0]);

PdfFormWidget formWidget = doc.Form as PdfFormWidget;
List xfafields = formWidget.XFAForm.XfaFields;
int count = xfafields.Count;

sorry, but what is the equivalent in Java ?

Also is there a way to separate Dynamic XFA PDF and Static XFA PDF; a sit seems that the first is problematic ?
Or to move from the first to the second one (flattening ?)

Hello,

I apologize. Please take a look at the following Java code.

Code: Select all

PdfFormWidget formWidget = (PdfFormWidget)doc.getForm();
List xfafields = formWidget.getXFAForm().getXfaFields();
int count = xfafields.size();

As for your proposed solution, I am sorry to say that we cannot achieve it at the moment. We do not have robust support for XFA yet because it is quite complex, but we are currently working hard to improve this.

I understand that the problem is hard. If google has this problem with chrome, it's not going to be an easy one

As a workaround, detecting that a PDF is a dynamic XFA PDF would be a good start, as this would allow to detect that there will be a problem.
Detecting XFA fields is not enough, as there can be some XFA fields *without* the PDF being dynamic.
so a method /code that would allow to detect the dynamic part would be nice

thanks
