CosDictionary expected, found class com.adobe.internal.pdftoolkit.core.cos.CosNumeric

[Former Community Member]

Hi,

I'm trying to merge xfa form with pdf using assembler service. For some pdf's it is working fine and for some I'm receiving the following error.

CosDictionary expected, found class com.adobe.internal.pdftoolkit.core.cos.CosNumeric, object Number of invalid cosObject:1036

Can anyone help me out.

Code used to merge in Assembler service:

<DDX xmlns="http://ns.adobe.com/DDX/1.0/">

  <PDF result="outDoc">

    <PDF source="coverpage" baseDocument="true">

      <NoXFA/>

    </PDF>

    <PDF source="inPDFDoc"/>

    <NoForms/>

  </PDF>

  <?ddx-source-hint name="coverpage"?>

  <?ddx-source-hint name="inPDFDoc"?>

</DDX>

Image of the error:

Thanks in advance..

Are you able to merge using Acrobat?

Hi Ramu,

Which LiveCycle version are you using? Can you please pass on the set of PDFs for which you are facing this issue?

[Kosta_Prokopiu1]

@marcusw76547027 : what this basically says is that one of the PDF documents used by your DDX commands is invalid or corrupted or contains invalid elements. CosDictionary errors are thrown when it cannot read the dictionary (for example if the PDF is actually not a PDF).  

[marcusw76547027]

But I can open the PDF file that causes this issue with the AssemblerService of AEM Forms in the Adobe Acrobat Reader 2017 without any problems. So the PDF file seems to be not invalid or corrupted.

[Kosta_Prokopiu1]

is this part of a JEE orchestration or AEM Workflow? How do you execute the DDX?

[marcusw76547027]

I use SOAP to call the AssemblerService.invoke method and pass the DDX and the input PDF documents as parameters.

[Kosta_Prokopiu1]

can you post your DDX here to see what you are trying to do?

[marcusw76547027]

<?xml version="1.0" encoding="UTF-8"?> <DDX xmlns="http://ns.adobe.com/DDX/1.0/"><PDF result="out.pdf"><NoXFA flatten="true"/><NoForms/><PDF source="0.pdf"/></PDF></DDX>

[Kosta_Prokopiu1]

I took your DDX and tested with a number of different PDFs. Obviously you want to flatten an XFA based formand your DDX does exactly that. Which brings me to believe that either something goes wrong when you upload your 0.pdf via SOAP or this particular PDF is corrupted in some way. Just to confirm: you can flatten other forms ok? It is only this or certain documents that do not work?

[marcusw76547027]

Yes I can flatten other PDF files with the exact same DDX without any problems. Only with some PDF files it generates this exception.
