I've started today using Sencha Touch and ran into some trouble. I hope you guys can help me a bit.

I've a list of customers and when i click on the disclosure button i want to display more detail of them in a from. Everything is working fine when displaying the detail is a simple Panel but when using a form in my view thing go wrong.

My model
Code:
Ext.define('SSL.model.Klant', {
    extend: 'Ext.data.Model',
    
    config: {
        fields: ['seqklant', 'naam1', 'naam2', 'adres1', 'adres2', 'adres3', 'btw', 'tel', 'gsm', 'email']
    }
})
My store
Code:
Ext.define('SSL.store.Klanten', {
   extend: 'Ext.data.Store',
   
   config: {
       model: 'SSL.model.Klant',
       sorters: 'naam1',
       grouper: function(record){
         return record.get('naam1')[0];  
       },
       autoLoad: true,
       proxy:{
            type: 'jsonp',
            url: 'http://localhost/SSL/json.php',
            reader:{
                type:'json',
                rootProperty: 'responseData'
            }
        }
   }
});
My controller
Code:
Ext.define('SSL.controller.Klant', {
    extend: 'Ext.app.Controller',
    
    config: {
        refs: {
            klantView: 'KlantContainer'
        },
        control: {
            'KlantLijst': {
                disclose: 'showDetail'
            }
        }
    },
    
    showDetail: function(list, record){
        this.getKlantView().push({
            xtype: 'KlantDetail',
            title: record.data['naam1'],
            data: record.data
        });
    }
})
And last but not least my View
Code:
Ext.define('SSL.view.KlantDetail', {
    extend: 'Ext.form.Panel',
    xtype: 'KlantDetail',
    
    config: {
        items: [{
            xtype: 'fieldset',
            items: [
                {
                    xtype: 'textfield',
                    name : 'naam1',
                    label: 'Name',
                    tpl: '{naam1}',
                    readOnly: true
                }
            ]
        }]
    } 
})
As you can see i try to obtain data from my store through my controller by assigning data to the record.data. When i used a simple Panel and a tpl i could obtain my data, but now when i'm using a from to display my data with a tpl it doesn't work anymore.

Which is a correct way to obtain data in my form ?

Thx in advance!
