You may want to filter the sub stores that each list gets.

Hi,

Hahahaha…. I finally found it !! I created a workaround to filter the nested list

Ok lets assume the default documentation data :

var data ={    name:'Don Griffin',    title:'Senior Technomage',    company:'Sencha Inc.',    drinks:['Coffee','Water','More Coffee'],    kids:[{ name:'Aubrey',  age:17},{ name:'Joshua',  age:13},{ name:'Cale',    age:10},{ name:'Nikol',   age:5},{ name:'Solomon', age:0}]};

Your model should have the following fields :

fields : [
{name : 'name', type : 'string'},
{name : 'title', type : 'string'},
{name : 'company', type : 'string'},
{name : 'drinks', type : 'auto'},
{name : 'kids', type : 'auto'},       //This is the important one
{name : 'age', type : 'integer'},
]

Now, if you want to filter your nestedList and only show the parents who (say) have a kid named "Cale" you do the following :

1. Don't make a nested list component. Make only a list component and feed it the nested data above.
2. Use the filterBy function as below :

MyApp.stores.ListStore.filterBy(function(record,id){
var theseKids = record.data.kids;   //This takes the kids array using the "auto" type from the data and       
                                                       //feeds it into our variable.
var flag = false;
for(var i=0; i<theseKids.length; i++){
if(theseKids[i].name.indexOf('Cade') != 0)
flag = true;
} 
return flag;
});

Now to the user it still looks like a nested list is being filtered
If you need the data to look like a nested list all you need to do is use the NavigationView component to pull the data from the itemTap event and push a new view of a list with that array of data.

Cheers
Hope this helps somebody
