Combining PDF Attachments with DDX, then send separately with Document of Record in AEM OSGi Workflow

I have a dynamic number of pdf attachments as input from an adaptive form, and would like to merge all attached pdfs into a single pdf using DDX, then have it send separately with the Document of Record with the Send Email step. However I encountered an issue with the Send Email step with the following: 

 

Caused by: com.adobe.granite.workflow.WorkflowException: GetPropertyValue failed as value corresponding to VARIABLE:attachments for type class java.lang.Object is NULL

 

 

The DDX is as follows:

 

<DDX xmlns="http://ns.adobe.com/DDX/1.0/"> <PDF result="Attachments.pdf"> <PDF source="fileAttachment"/> </PDF> </DDX>

 

 

Input map for invoke ddx:

The "attachment" path matches the output attachment folder of the adaptive form

Output map:

The output document is saved into the "attachments" document variable

Send Email step with Document of Record and attachments document:

 

 I am unsure why the value for attachments is NULL. Any help on this is appreciated, thank you!

 

EDIT - testing workflowuser's process:

The following is the dynamic table with file attachments. The ordering is PDFs 1,2,3,4, but the resultant PDF from the process gives ordering 2,3,4,1.

      No, I am unable to since it requests for a password when combining

        Thank you! This is unrelated, but is it possible for secured PDFs to be merged with DDX without their passwords? The use case would be similar to Adobe Sign, where all attachments can be rendered and merged regardless if they are secured or not.

        I have also added bookmarks to the assembled pdf 

        open the assembled pdf using Adobe reader and check the bookmarks

          Here is the latest bundle

          https://documentcloud.adobe.com/link/track?uri=urn:aaid:scds:US:6c353e00-1139-48c6-b8b3-5bd4abda5fd5

          I have increased the size of my query to 100

          Your workflow step should look like this

            As a workaround have two repeating panel’s. The first panel you can allow users to add a maximum of say 12 attachments 

            In the second panel they can add another 8 attachments and submit the form 

            this is working for me

              Is that a common use case of attaching 20 pdf files?

                It is an uncommon use case, but there may be times where there are 20+ attachments.

                  Did you enable the log for the bundle?

                  check the logs it should give you more information 

                  Are these attachments all pdf files?

                      Hi Giresh, i was able to resolve the repeating panel issue by adding a subform in the xdp and rewriting the schema. Thank you

                      your Data.xml should look something like this. It should have fileAttachment elements in it

                      <?xml version="1.0" encoding="UTF-8" standalone="no"?>
