DOJO 1.7: Child properties access on JSON + DataGrid

Katakan kita diberi data JSON:

[{"id":{"chmCompanyCode":"U","chmCollegeCode":"BMI","chmBlockCode":"SB-A","chmHouseCode":"1F-18"},"chmActive":"Y","chmCapacity":4,"chmCurCapacity":4,"chmFreeCapacity":0,"chmHouseDesc":"LEVEL 1","chmLevel":1}]


Untuk akses id.chmHouseCode dan set pada layout untuk datagrid:

gridLayout = [
{ name: "id", field: "id"},
{ name: "Code", field: "_item", formatter:function(item){return item.id.chmHouseCode;}},
{ name: "Name", field: "chmHouseDesc"},
{ name: "Capacity", field: "chmCapacity"}];


Cuma ubah BLUE FONT sahaja, yang lain maintain.


Masalahnya, tak boleh sorting apabila gunakan _item atau get.
