Using ddx to create pdf package

[kc]

Hi all,<br /><br />I have a process which handles a number of forms (3 or 4 depending on the routes chosen).<br /><br />Along the process i store the forms as documents and add them to a list variable. In the end of the process I call a subprocess with this list as input and this process uses a ddx-file for assembling a pdf-package that can be presented as an overview/result of a specific invocation. The ddx-file looks like this:<br /><br /><?xml version="1.0" encoding="UTF-8"?><br /> <DDX xmlns="http://ns.adobe.com/DDX/1.0/"><br /> <PDF result="GeneratedDocument.pdf"> <br /> <PackageFiles> <br /> <PDF source="attachments"/><br /> </PackageFiles> <br /> </PDF><br /> </DDX><br /><br />The map that I use as input for the invokeDDX service is created like this:<br /><br />/process_data/ddxMap[@id="attachments"] = /process_data/ddxList<br /><br />After this step the ddxList variable has the size 3 and the ddxMap variable has a size of 1. Is this not the correct approach?<br /><br />Post is continued below:

The AssemblerResult looks like this, and I can not see where it is wrong:

I try to get the result document in the following manner:

/process_data/outDoc = /process_data/AssResult/object/documents[@id="result"]

However this gives me the following output in the server.log:

2008-10-26 19:35:03,583 INFO [com.adobe.livecycle.assembler.AssemblerServiceImpl] ALC-ASM-N00-001: Execute: invokeDDX() begin on thread JMS SessionPool Worker-34 32009

2008-10-26 19:35:04,192 INFO [com.adobe.livecycle.fileutils.FileUtilsService] Null document. 'writeDocument' operation not completed

The writeDocument fails because the document that I try to save in a doc varioble seems to be null.

Can anyone help me understand why this is the case? I must have over looked something...

Hi again,



I think I solved this one myself, I had made an error when fetching the result document of the AssemblerResult.



So you need:



/process_data/AssResult/object/documents[@id="GeneratedDocument.pdf"] and not like I initially did (I saw this mistake in the documentation):



/process_data/outDoc = /process_data/AssResult/object/documents[@id="result"]



Hope you can use this info

hi,



I'd like to better understand the error that you found in the documentation so that I can correct it.



http://livedocs.adobe.com/livecycle/8.2/wb_help/001031.html says that if the assembled document is a single document, the logical name of the document is the value of the result attribute that is specified in the DDX.



This seems to correctly predict the XPath expression that you used. But I can't find where the docs say to use 'relult' as the logical name of the document.



thanks

Hi again Scott,



Thank you for responding, I might have been too quick on my judgement of the documentation there. I was struggling with this problem and was trying to find inspiration from where ever I could ;o).



There fore I have found the line



/process_data/outDoc = /process_data/AssResult/object/documents[@id="result"]



NOT in the documentation but in a Sample called LetterWithAttachment. Here it is in the next to last step called "Extract Output from Assembler Result - Set Value".



So I apologize for the mistake, the documentation does not state the above mentioned assignment. However I would haver liked the example in the documentation to be more illustrative.
