"Drools XML error when passing process variables to work item" To view the discussion, visit: https://community.jboss.org/message/811284#811284 -------------------------------------------------------------- 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'. | | 5 | 02/05 11:43:16,410[main] ERROR drools.xml.ExtensibleXmlParser.error - (null: 41, 64): cvc-id.2: There are multiple occurrences of ID value '_4_Start_DateInput'. | | 5 | 02/05 11:43:16,410[main] ERROR drools.xml.ExtensibleXmlParser.error - (null: 41, 64): cvc-attribute.3: The value '_4_Start_DateInput' of attribute 'id' on element 'dataInput' is not valid with respect to its type, 'ID'. | | 6 | 02/05 11:43:16,411[main] ERROR drools.xml.ExtensibleXmlParser.error - (null: 42, 60): cvc-id.2: There are multiple occurrences of ID value '_4_End_DateInput'. | | 6 | 02/05 11:43:16,411[main] ERROR drools.xml.ExtensibleXmlParser.error - (null: 42, 60): cvc-attribute.3: The value '_4_End_DateInput' 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.
