Problem with assembling flattened PDFs with XFA docs


Level 2
I have a flattened PDF (legacy) doc that I am sending into a livecycle process to merge with an XFA doc that I am creating on the server. Assembler will not allow me to assemble the docs in the following order:

1. flattened PDF

2. XFA doc

I CAN do the reverse order just fine. Problem is order DOES matter and I need the XFA last.

Any thoughts on how I can reach that end result? I was thinking of doing the merge in the wrong order and then maybe reordering the pages, but don't know how to do that either.

Any help would be VERY appreciated!

Try specifying the xfa doc as the base document, i.e.:

<PDF result="out">

<PDF source="flatPDF"/>

<PDF source="xfa" baseDocument="true"/>
