Merging PDFs with Signature Blocks

Problem Description: I have a PDF form built in LiveCycle that contains a signature block. After filling multiple copies of the form using cfpdfform inside a cfloop, I am flattening and then attempting to merge them into one PDF using cfpdf action=merge. The PDFs merge, but the signature block can only be signed on the first and last pages of the merged PDF. Pages in the middle just have a blank, unsignable box.

Steps to Reproduce: 

Actual Result: For merging two forms, just the last page has a signable block. For three or more, the first and last pages have a signable block.

Expected Result: It would be nice to have a signable signature block on every page of the merged PDF.

Any Workarounds: Processing one PDF at a time and not merging them.

If I don't flatten it just duplicates data from the last PDF of the series. Flattening a single PDF does preserve the signing capability.

Hi paul, Can you please send me the pdf that you are using? I tested in my LiveCycle PDF and it has the signature blocks on every page. Thanks & Regards, Suchika.

Sorry for the delay between communications. I was able to reproduce this using the following code: <cfpdf action="merge" source="form 1.pdf, form 2.pdf, form 3.pdf, form 4.pdf, form 5.pdf, form 6.pdf" destination="form merge.pdf" overwrite="yes"> I will attach three PDFs displaying the behavior I am seeing.

Adobe, Repro is very simple (it'll take you 2 minutes): 1) Download the 3 PDFs Paul attached to this ticket 2) Run <cfpdf action="merge" source="form merge 2 pages.pdf,form merge 3 pages.pdf,form merge 6 pages.pdf" destination="form merge.pdf" overwrite="yes"> 3) Open "form merge.pdf" and see all signature blocks (except the first and last) are unsignable (bug) Verified in CF11 Update 5 (build 11,0,05,293506). Tho he filed this for CF10 so it should also be fixed in a CF10 update. Thanks!, -Aaron

I can also attach the original source PDFs if that will help. The PDFs currently attached are the results from merging already. Aaron - thanks for reproducing.

Unfortunately, this is a current design limitation and will not be fixed given that this is an edge case. Also, Acrobat doesn't support this.
