Trying to consume .Net webservice in Coldfusion 10, wdsl giving me headaches - coldfusion

Question

I have been a coldfusion developer since 1999 but the last few years I have been working more with other technologies.
Recently I have been asked to implement a client for a webservice that allows one to order pharmacists medicines at a wholesale depot.
The full service description can be found here:
http://services.bitler.be/GenericServices/OrderProcessingService.svc?singleWsdl
I think the relevant sections for consuming the client are the following ones, but feel free to look at the full description in case I missed anything:
The function: <wsdl:operation name="ProcessOrder">
The expected parameters:
<xs:complexType name="OrderProcessingRequest">
<xs:complexContent mixed="false">
<xs:extension .... base="q1:RequestBase">
<xs:sequence>
<xs:element minOccurs="0" name="CustomerEmail" nillable="true" type="xs:string"/>
<xs:element minOccurs="0" name="ProcessOrderLines" nillable="true" type="tns:ArrayOfProcessOrderLine"/>
<xs:element ... minOccurs="0" name="Site" type="q2:FebelcoSite"/>
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
<xs:element name="OrderProcessingRequest" nillable="true" type="tns:OrderProcessingRequest"/>
<xs:complexType name="ArrayOfProcessOrderLine">
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="unbounded" name="ProcessOrderLine" nillable="true" type="tns:ProcessOrderLine"/>
</xs:sequence>
</xs:complexType>
<xs:element name="ArrayOfProcessOrderLine" nillable="true" type="tns:ArrayOfProcessOrderLine"/>
<xs:complexType name="ProcessOrderLine">
<xs:sequence>
<xs:element minOccurs="0" name="ProductNumber" nillable="true" type="xs:string"/>
<xs:element minOccurs="0" name="QuantityRequested" type="xs:int"/>
</xs:sequence>
</xs:complexType>
<xs:element name="ProcessOrderLine" nillable="true" type="tns:ProcessOrderLine"/>
<xs:complexType name="RequestBase">
<xs:sequence>
<xs:element minOccurs="0" name="ApbNumber" nillable="true" type="xs:string"/>
<xs:element minOccurs="0" name="BSKey" nillable="true" type="xs:string"/>
<xs:element minOccurs="0" name="WholesalerId" type="xs:int"/>
</xs:sequence>
</xs:complexType>
<xs:element name="RequestBase" nillable="true" type="tns:RequestBase"/>
This is what I have come up with so far:
cffunction name="placeOrder" access="remote" returntype="any">
<cfargument name="apbnr" required="yes" type="string">
<cfargument name="bskey" required="yes" type="string">
<cfargument name="cnk" required="yes" type="string">
<cfargument name="quantity" required="yes" type="string">
<cfargument name="site" required="yes" type="string">
<cfscript>
orderProcessingRequest = StructNew();
orderProcessingRequest.apb = apbnr;
orderProcessingRequest.bskey = bskey;
orderProcessingRequest.vestiging = site;
productOrderLines = ArrayNew(1);
productOrderLine = StructNew();
productOrderLine.cnk = cnk;
productOrderLine.quantity = quantity;
productOrderLines[1] = productOrderLine;
orderProcessingRequest.productOrderLines = productOrderLines;
ws = CreateObject("webservice", "http://testservices.bitler.be/GenericServices/OrderProcessingService.svc?singleWsdl" );
newOrder = ws.ProcessOrder(orderProcessingRequest);
writeoutput(newOrder);
</cfscript>
</cffunction>
But it keeps throwing me errors at the line the function is invoked.
I suspect I have an error in the "orderProcessingRequest", but I honestly can't figure out where.
Cannot perform web service invocation ProcessOrder.
The fault returned when invoking the web service operation is:
org.apache.axis2.AxisFault: There was an error while requesting your data. Please contact Bitler support with error ref (O150214084734).

Recently I was having some trouble with a webservice after moving from CF 9 to CF 10. We were connecting to the webservice via HTTPS so we had to import it's SSL certificate into the JVM (not relevant to you since I see that you are using a webservice via HTTP) and use {wsversion="1",refreshwsdl="true"} ?
What happens when you try changing it from
ws = CreateObject("webservice", "http://testservices.bitler.be/GenericServices/OrderProcessingService.svc?singleWsdl" ); //, { refreshWSDL=true, wsversion=1 }
to
ws = CreateObject("webservice", "http://testservices.bitler.be/GenericServices/OrderProcessingService.svc?singleWsdl", { refreshWSDL=true, wsversion=1 } );
?
