php json_encoded array and nestedlist

[essex]

Hello,

Is there anything special that needs to be done to special to make an array work in the nested list besides JSON encoding it in PHP. I have tried several times to prepare my array for the nested list but I get nothing.

here is the code that produces my array

 foreach ($channels as $index => $c)
            {
                $node = $c['Content']['call_letters'];
               // var_dump($node);
              //  exit();
            
                 if ($node == $c['Content']['call_letters'])
                 {
                    //$refactor[$node][$index] = $c['Content'];
                   
                    $refactor[$node][$index] =
                    array('text' => $node,
                        'items'=> $c['Content']
                       );
                 }           

            }

here is my array:

array   'KKYO' =>      array       0 =>          array           'text' => string 'KKYO' (length=4)           'items' =>              array               '_id' => string '4f128b336930f31137081969' (length=24)               'call_letters' => string 'KKYO' (length=4)               'channel_name' => string 'KKYO-Kyoto' (length=10)               'bcast_channel' => int 100               'start_time_utc' => float 1326650400               'program_id' => string '99344001' (length=8)               'title' => string 'Kyoto' (length=5)       1 =>          array           'text' => string 'KKYO' (length=4)           'items' =>              array               '_id' => string '4f128b336930f3113708196a' (length=24)               'call_letters' => string 'KKYO' (length=4)               'channel_name' => string 'KKYO-Kyoto' (length=10)               'bcast_channel' => int 100               'start_time_utc' => float 1326657600               'program_id' => string '99344001' (length=8)               'title' => string 'Kyoto' (length=5)       2 =>          array           'text' => string 'KKYO' (length=4)           'items' =>              array               '_id' => string '4f128b336930f3113708196b' (length=24)               'call_letters' => string 'KKYO' (length=4)               'channel_name' => string 'KKYO-Kyoto' (length=10)               'bcast_channel' => int 100               'start_time_utc' => float 1326664800               'program_id' => string '99344001' (length=8)               'title' => string 'Kyoto' (length=5)

my nested list code

Ext.setup({
    name: 'mapp',
    onReady: function() {
        Ext.define('Channels', {
            extend: 'Ext.data.Model',
        fields: [
                        {
                            name: "text",
                            type: "string"
                        }
                        ]
        });

        channelstore = Ext.create('Ext.data.TreeStore', {

        channelPanel = Ext.create('Ext.NestedList', {
            fullscreen: true,
            title: 'Channels',
            displayField: 'text',
            store: channelstore

            console.log(channelstore);
    }
});

Any input is greatly appreciated.
