Hi everybody! I have a problem and I can't resolve it!
I have a dataview with some images, this is my code:

var imageView = new Ext.DataView({
    id: 'imageView',
    store: catalogoStore,
    itemSelector: 'div.thumb-wrap',
    multiSelect: false,
    '<div class="contenedor2" align="center">' +
    '<span id="dlModelos" class="hidebr">' +
    '<tpl for=".">' +
    '<div class="thumb-wrap"><img src="{url}" title="{name}" width="500" height="500"><br /><br />' +
    '</tpl>' +
    '</span>' +

var imageForm = new Ext.form.FormPanel({
    id: 'imageForm',
    fullscreen: true,
    layout: 'fit',
    cardAnimation: 'slide',
    scroll: 'vertical',
    dockedItems: [
        xtype: 'toolbar',
        title: 'Material'
    items: [imageView]

catalogoView = Ext.extend(Ext.Panel,
    id: 'catalogoView',
    fullscreen: true,
    layout: 'card',
    cardAnimation: 'slide',
    items: [imageForm]

Ext.reg('catalogoView', catalogoView);

It works fine but when I try to expand the image with my two fingers, nothing happens, the image just move but nothing more, what do I have to do? Please!

Thanks in advance
