TreeGrid: setting data root has no effect

Question

I\'m trying to setup a TreeGrid, my data object looks like this:

{
    \"code\": \"success\",
    \"data\": {
        \"text\": \".\",
        \"children\":

You can also use this:

        reader: {
        type: 'json',
        // See http://stackoverflow.com/questions/9159627/extjs-loading-tree-from-json-file-using-mvc
        // http://stackoverflow.com/questions/6263380/extjs4-json-treestore
        root: function(o) {
            if (o.data) {
                return o.data;
            } else {
                return o.children;
            }
        }
    },
