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.

I have increased the size of my query to 100

Your workflow step should look like this
