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'. |

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?

The Work Item Handler is:

}
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:

[
"name" : "IP Conversations",
"parameters" : [
