How to set the value of WSDL input parameter on fetch?

[francisu]

I'm using the 2011-05-17 Nightly

I'm trying to use data binding to WSDL and to bind a ListGrid to a WSDL data source and do a fetch on it and have it return the values and automatically populate the fields.

The first parameter of my request operation is a SessionId (see below for the JS encoded message). I want to populate this with the value of a global variable. I'm using the code below to do this.

However the SessionId argument is not being emitted in the call. I can't find anywhere in the documentation that describes how to explicitly set the arguments of a WSDL request operation short of using a WebService.callOperation(), but using this does not give me the data binding. I looked at the Salesforce example and the SessionID there is not an argument to the SOAP method but an extra parameter in before it.

So I'm a bit stuck. Can you help?

		var tradingPartnerDs = isc.DataSource.create({
			serviceNamespace : ws.serviceNamespace,
			wsOperation : "TPList",
			fields : [ {
				name : "ECGridID"
			}, {
				name : "NetworkID"
			}, {
				name : "NetworkName"
			} ],
			operationBindings : [ {
				operationType : "fetch",
				wsOperation : "TPList",
				recordName : "TPList"
			} ]
		});

		tradingPartnerDs.addMethods({
			transformRequest : function(dsRequest) {
				if (dsRequest.operationType == "fetch") {
					console.log("fetch sessionId: " + sessionId);
					var params = {
						SessionId : sessionId
					};
					return isc.addProperties({}, params, dsRequest.data);
				}
			}
		});

The WSDL operation:

        isc.XSElement.create({
            ID:"TPList",
            mustQualify:true,
            fields:{
                SessionID:{
                    name:"SessionID",
                    type:"string",
                    xmlMinOccurs:0,
                    xmlRequired:false
                },
                ShowInactive:{
                    name:"ShowInactive",
                    type:"boolean",
                    xmlRequired:true
                }
            }
        })

First thing that jumps out is mismatched case (SessionId and SessionID).

Please don't post issues with WSDL without posting the full .wsdl file and any associated .xsds, otherwise, obviously we cannot troubleshoot it.
