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">
<start name="start1" g="236,45,48,48">
<transition name="to localGetSettlementFileChecker" to="localGetSettlementFileChecker" g="-135,-22"/>
</start>
<decision name="localGetSettlementFileChecker">
<handler>
<field name="fromVariable"><string value="farDirectoryFiles"/></field>
</handler>
<transition name="yes" to="moveFileDownloadAct" />
<transition name="no" to="t_end" />
</decision>
<custom name="moveFileDownloadAct" g="185,140,133,52" class="com.workFlowProcessor.actions.MoveFileActivity">

</process>
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.
