Accessing ChildNode data in Nested List

[Sasha172]

Hi,

I have a nested list component that is structured as follows :

{
    "items":[
                {
                  "text": "Parent 1",
                  "leaf": false,
                  "items": [
                    {
                      "text": "Child 1",
                      "leaf" : true
                     },
                    {
                      "text": "Child 2",
                      "leaf" : true
                     },
                    {
                      "text": "Child 3",
                      "leaf" : true
                     },

                    ]
                   },
                {
                  "text": "Parent 2",
                  "leaf": false,
                  "items": [
                    {
                      "text": "Child 1",
                      "leaf" : true
                     },
                    {
                      "text": "Child 2",
                      "leaf" : true
                     },
                    {
                      "text": "Child 3",
                      "leaf" : true
                     },

                    ]
                   } ] }

As of now Im using the Ext.Nested list component to navigate thru the list as so : Parent1>Child1>detailCard etc

However, I want to add a functionality such that : On clicking the Parent1 element in the list an alert should display how many Child objects it has in its items array.

How do I go about that ?

Thanks in advance
Sasha

I should probably add that this is my store :

bus_store = new Ext.data.TreeStore({    model: 'ListItem',
    //root: data,
    proxy: {
        type: 'ajax',
        url: 'data/routes.json',
        reader: {
            type: 'tree',
            root: 'items'
        }
    }
});

And this is my NestedList

..........

BusView = Ext.extend(Ext.NestedList, {
      
      id: 'nestedList',
      title: 'Bus View',
      iconMask: true, 
      ui: 'plain',
      iconCls: 'locate',
      fullscreen: true,
      store: bus_store,
      displayField: 'text', 
...........

This looks like a Sencha Touch question to me. This forum is for ExtJS 4. You may have more luck getting an answer in the Sencha Touch forum.
