"Drools XML error when passing process variables to work item"

I've been reading through "Section 7.2.3, Using your new work item in your
processes" to see how to pass process variables to a work item. Even though the
values of each process variable are getting passed each work item, I'm getting the
following XML error in the Eclipse console:
| 1 | 02/05 11:43:16,406[main] ERROR drools.xml.ExtensibleXmlParser.error - (null: 40,
62): cvc-id.2: There are multiple occurrences of ID value '_4_Source_IPInput'. |
| 4 | 02/05 11:43:16,409[main] ERROR drools.xml.ExtensibleXmlParser.error - (null: 40,
62): cvc-attribute.3: The value '_4_Source_IPInput' of attribute 'id' on
element 'dataInput' is not valid with respect to its type, 'ID'. |

*parameters passed into work item: 111.111.111.111, 2013 05 02 09:00:00, 2013 04 02
09:00:00*
Note the last line in red shows the values are being passed. Does anyone see anything in
the folllowing that would cause the Drools XML error?
**********
public class ProcessMain {
public static final void main(String[] args) throws Exception {
// load up the knowledge base
KnowledgeBase kbase = readKnowledgeBase();
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
// start a new process instance
Map<String,Object> params = new HashMap<String,Object>();
params.put("processIP", "111.111.111.111");
params.put("processStartDate", "2013 05 02 09:00:00");
params.put("processEndDate", "2013 04 02 09:00:00");
ksession.getWorkItemManager().registerWorkItemHandler("IP
Conversations", new IPConversationsWorkItemHandler());
ksession.startProcess("com.sample.bpmn.hello",params);
}
private static KnowledgeBase readKnowledgeBase() throws Exception {
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("sample.bpmn"),
ResourceType.BPMN2);
return kbuilder.newKnowledgeBase();
}
}
***********
The Work Item Handler is:
**********
package com.sample;
import org.drools.runtime.process.WorkItem;
import org.drools.runtime.process.WorkItemHandler;
import org.drools.runtime.process.WorkItemManager;
import java.sql.*;
import java.util.*;
public class IPConversationsWorkItemHandler implements WorkItemHandler {
public void executeWorkItem (WorkItem workItem, WorkItemManager manager) {
// extract parameters
String sourceIP = (String) workItem.getParameter("Source_IP");
String startDate = (String) workItem.getParameter("Start_Date");
String endDate = (String) workItem.getParameter("End_Date");
System.out.println("parameters passed into work item: " + sourceIP +
"," + startDate + "," + endDate);
// notify manager that work item has been completed
manager.completeWorkItem(workItem.getId(),null);
}
public void abortWorkItem (WorkItem workItem, WorkItemManager manager) {
// do nothing, not planning to abort operation at this time
}
}
*********
*********
The work item definition file has the following entry:
import org.drools.process.core.datatype.impl.type.StringDataType;
[
[
"name" : "IP Conversations",
"parameters" : [
"Source_IP" : new StringDataType(),
"Start_Date" : new StringDataType(),
"End_Date" : new StringDataType()
],
"results" : [
"Source_IPs" : new StringDataType(),
"Source_Ports" : new StringDataType(),
"Dest_IPs" : new StringDataType(),
"Dest_Ports" : new StringDataType(),
"Recv_Time" : new StringDataType()
],
"displayName" : "IP Conversations"
],
]
