Disassembling documents:

Hi,

  I'm trying to disassemble documents. My Assembler input is a map document with ddx:

<PDFsFromBookmarks prefix="stmt">

     <PDF source="doc1.pdf"/>

</PDFsFromBookmarks>

What should be the output give for this service in Assembler process? I tried to give the output a variable
of type Assemblerresult. (error: Cannot create a map entry without a key specified)

What should be the key entry we need to provide? I also tried using a variable of type map in the output
parameter with subtype AssemblerResult. Still I see the same output. I think I'm missing something in doing 
this for the output parameter. 

Please help. I was struggling all the weekend trying different combinations for the output. Unfortunately, 
i could not find any sample that shows disassembling documents.

Thanks,
Chaitanya
