Kendo Grid / JSDO / Not returning single table in multi-tabl

Hi All 

I have a very simple Kendo Grid:

dataSource = new kendo.data.DataSource( {type: "jsdo",

serverPaging: true,

serverFiltering: true,
// filter: { field: "Country", operator: "eq", value: "USA" },
serverSorting: true,
// sort: { field: "State", dir: "desc" },
pageSize: 10,
transport: {
jsdo: "OEAA.Repairs.LocationListBusinessEntity",

tableRef: "eLocListEntries",

// viewTables can be used as a comma separated list to selectively fill
// child/grandchild tables of the tableRef specified above. By default
// if querying top level table in the dataset, all children are returned
// if querying a child table, only the child table will be returned. Can
// also use wildcards in the comma separated list e.g. eJob*
viewTables: "",
countFnName: "count"
},

The JSON returned is of the format:

{
"dsLocationList": {
"eLocList": [{
"OrgCode": "01",
"ClientCode": "",
"LocList": "PB",
"Description": "PB",
"NoOfLocations": 0,
"Inactive": false,
"CustomUIResponse": null,
"id": "01||PB",
"seq": null
}, {
"OrgCode": "01",
"ClientCode": "HSG",
"LocList": "BOIL",
"Description": "boiler scheme II",
"NoOfLocations": 2,
"Inactive": false,
"CustomUIResponse": null,
"id": "01|HSG|BOIL",
"seq": null,
"eLocListEntries": [{
"OrgCode": "01",
"ClientCode": "HSG",
"LocList": "BOIL",
"PlaceRef": "1000191",
"Address": "46 Stanhope Park Drive, Carlisle, Cumbria, CA1",
"LocationStatus": "O",
"LocationStatusDescription": "Occupied",
"LocationSubStatus": "OCC",
"LocationSubStatusDescription": "Occupied",
"JobAllowed": "Y",
"CustomUIResponse": null,
"id": "01|HSG|BOIL|1000191",
"seq": null
},

But the grid is empty.

Any ideas?

Thanks
