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"
  ],
]
