--------------------------------------------------------------
Hi Guys,
I'm pretty new to jBPM and am seeing a couple of issues that hopefully someone can \
help with.
I have a workflow that basically parses a set of XML files and moves these to \
different directories depending on the stage of the processing and the overall \
outcome. If there is only one file to process this workflow is fine but once I add \
another file I start seeing exceptions from JBPM.
JBPM: 4.0 (but have also tried 4.2 with the same errors)
Spring 3
JBoss 5.0.1GA
My workflow is setup as:
<?xml version="1.0" encoding="UTF-8"?>
<process id="settlementProcessor" name="settlementProcessor" xmlns=" \
http://jbpm.org/4.0/jpdl http://jbpm.org/4.0/jpdl">

value="farDirectoryFiles"/></field> </handler>

This is the exception I'm getting:

Does anyone know what the problem could be? I could try this out on 4.3/4.4 but \
would like to understand what the problem is before I do.
Any help is much appreciated.
