SAPUI5 : How to use Content ID for the ODataV2 version

[pulla]

Hi Guys,

Am trying to use content Id for my associations and am also using the V2 Odata Model.For this am using the below code and it is not working.

Regards-Pulla.

		sPath = "/OrderSet('" + oDataSave.OrderId + "')";


				oDataModel = this.getModel();
				oDataModel.setDeferredGroups(["myId"]);
				oDataModel.setChangeGroups({
					"Order": {
						groupId: "myId",
						changeSetId: "Test",
						single: true
					}
				});


				Etag = oDataModel.getETag(sPath);
				mParameters = {
					success: function(oData) {


						MessageToast.show("Data successfully Saved!");
					},
					error: function(sError) {
						jQuery.sap.log.info("FYI: something has happened and it is a data error");
					},
					eTag: Etag,
					groupId: "myId",
					changeSetId: "Test",
					merge: false
				};


				oDataModel.update(sPath, oDataSave, mParameters);


				sPath = "/OrderSet('" + oDataSave.OrderId + "')" + "/ToOrderLocation";
				mParameters = {
					success: function(oData) {
						jQuery.sap.log.info("FYI: it is success");
					},
					error: function(sError) {
						jQuery.sap.log.info("FYI: something has happened and it is a data error");
					},
					groupId: "myId",
					changeSetId: "Test",
					merge: true


				};


				oDataModel.update(sPath, {OrderId: oDataSave.OrderId,WellId:"100247"}, mParameters);
				oDataModel.submitChanges();
			}
