How I can use variables in Adobe OSGI DDX Assembler like we are used in Livecycle ES4 DDX

We used workflow variables in DDX assembler with Livecycle ES4 JEE. Like this:

<DDX xmlns="http://ns.adobe.com/DDX/1.0/">
  <PDF result = "myPDF">
    <Watermark scale="70%" verticalOffset="-85pt" opacity="100%">
        <PDF source = "docLoteDeclaracoes" pages="{$/process_data/@intPagina$}"/>
    </Watermark>
    <PDF source = "docModeloAnexo"/>
  </PDF>
  <?ddx-source-hint name = "docLoteDeclaracoes"?>
  <?ddx-source-hint name = "docModeloAnexo"?>
</DDX>

In this code workflow process put value of page to be extracted from "docLoteDeclaracoes" in variable intPaginas.

I need to do similar thing using AEM Forms OSGI workflow, but this form to reference variables don't working.

Any one know how reference OSGI workflow variables in DDX document?

OBS: I am using AEM Forms 6.5

This is other solution for this case.

 

  1. Create one file with DDX commands.
<DDX xmlns="http://ns.adobe.com/DDX/1.0/"> <PDF result = "doc.pdf"> <PDF source = "docLoteDeclaracoes" pages="1"/> </PDF> <?ddx-source-hint name = "docLoteDeclaracoes"?> </DDX>
  1. Set one process variable type XML with file content.

 

  1. Update command XML Node with xpath for the content.

XPath: //PDF[@source="docLoteDeclaracoes"]/@pages

 

  1. Invoke DDX

    it's a little different in OSGI world. I will give you a custom OSGI bundle that will allow you to set the value of any xml element or attribute's value

    I have created custom OSGI bundle that allows you to set the value in DDX attribute as part of the workflow as shown in the screen shot

    The first parameter is the location of your DDX file. The second is the element and the third is the attribute , and fourth is the value that needs to be set

    After the attribute values are set, the DDX is updated in the original location

    You can set multiple attributes as shown in the screenshot

    The bundle is shared here.

    upload your DDX file into AEM DAM

    Deploy the bundle and create a simple workflow with the a process step. Set the process step arguments as shown in the screen shot

      Thanks @workflowuser. I already solved this putting DDX script into a XML variable and alter properties with a set Variables Step with a Xpath expression (//PDF[@source="docLoteDeclaracoes"]/@pages) to update required property. But I will test your Process Step bundle too.
