The output document of the Batch Processor service does not contain the content of the Input_Document

Symptom

The output document of the Batch Processor service does not contain the content of the Input_Document in GIS 4.1.1-1984.

I am attempting to use the batch processor service but while I can get the prefix ("<root>") added, the actual XML document to which I want to add the prefix is not included in the output document of the batch processor service. The XML document to which I should add the prefix is well-formed.

I do not actually want to modify the XML document (apart from adding the prefix) and therefore have created an Input document for the batch processor service that looks like this

<batchProcessor>

<fragment docname="Doc1">

</fragment>

</batchProcessor>

The BPML looks like this

<process name="TEST_BATCH_PROCESSOR">

<sequence>

<assign to="PrefixDocument"><root></assign>

<operation name="File System Adapter">

<participant name="File_System_Adapter"/>

<output message="FileSystemInputMessage">

<assign to="Action">FS_COLLECT</assign>

<assign to="collectionFolder">c:\collect</assign>

<assign to="deleteAfterCollect">false</assign>

<assign to="filter">REFERENCE.xml</assign>

<assign to="." from="*"></assign>

</output>

<input message="inmsg">

<assign to="." from="*"></assign>

</input>

</operation>

<assign to="Doc1" from="</assign</a>>

<assign to="InputDocument" from="</assign</a>>
