Simple SOA application, but error in load of wsdl wont compile

Question

Hi all,
I've come to the end of the line with this one, so I hope someone can help. I have a very simple business rules application - one function, one rule, one decision service - and the deployment descriptor (wsdl) copied at the bottom. When I try to compile the application I get:
Error: Load of wsdl "TrainDeliveryServiceCancelledNotificationRules_TrainDeliveryServiceCancelledNotificationRule_DecisionService_1.wsdl with Message part element undefined in wsdl [file:/C:/_dev/NROL3/Soa/Nrol3BusinessRulesPoc/TrainDeliveryServiceCancelledNotificationRules_TrainDeliveryServiceCancelledNotificationRule_DecisionService_1.wsdl] part name = payload     type = {http://xmlns.oracle.com/TrainDeliveryServiceCancelledNotificationRules/TrainDeliveryServiceCancelledNotificationRules_TrainDeliveryServiceCancelledNotificationRule_DecisionService_1}callFunctionStateful" failed
I am sure its me being thick, but I can't see what I'm doing wrong. I have a feeling my schema def headers for my data are wrong:
<xs:schema
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.customersharepoint.co.uk:8090/trac/TS1331_NROL3/wiki/xsd"
targetNamespace="http://www.customersharepoint.co.uk:8090/trac/TS1331_NROL3/wiki/xsd" elementFormDefault="qualified">
My wsdl is as follows. Jdev is giving me a warning on my custom application imports, but I dont think thats the problem.
Please help!

Well, after burning a half a day on this I've discovered that deleting and recreating the decision service makes the problem go away. This is not the first time that inexplicable problems in JDeveloper 11 have gone away after 'turning it off and on again'.
Anyone have any ideas?
