Unable to show data in ExtJS Tree Grid

Question

I just copied the example of ExtJS tree grid from Sencha's site. I created a fiddle with only difference being, I am using local data instead of using proxy & I have removed some columns.

Please check this fiddle and tell me why I am not able to see data in the grid?

Thank you!!!

Tree stores don't have a data option (search for it in the docs). Memory proxies, on the other hand, do. So you can put your data in it to solve your problem:

var store = Ext.create('Ext.data.TreeStore', {
    model: 'Task',
    proxy: {
        data: JData,
        type: 'memory'
    },
    folderSort: true
});
