    Default Answered: Problem Getting Images - Gallery PHP

    Hi everybody, I have a problem, I tried to show a simple panel with some images, I found a code on the Web and Im using a php to get the images, I also see this example in Sencha Documentation.
    I don't know what I doing wrong ... could you tell me what is the error in my code please?.
    I got a error "Uncaught Attempting to extend from a class which has not been loaded on the page" but still I can show the images.

    This is my code:

    Store:
    Code:
    var catalogoStore = new Ext.data.Store ({
        autoLoad: true,
        model: 'catalogoModel',
        proxy: {
            type: 'ajax',
            url: 'get-images.php',
            reader: {
                type: 'json',
                root: 'images'
            }
        }
    });
    Model:
    Code:
    Ext.regModel('catalogoModel', {    fields: [
            'name', 'url',
            { name: 'size', type: 'float' },
            { name: 'lastmod', type: 'date', dateFormat: 'timestamp' },
            'thumb_url'
        ]
    });
    View:
    Code:
    var tpl = new Ext.XTemplate(    '<tpl for=".">',
            '<div class="thumb-wrap" id="{name}">',
            '<div class="thumb"><img src="{thumb_url}" title="{name}"></div>',
            '<span class="x-editable">{shortName}</span></div>',
        '</tpl>',
        '<div class="x-clear"></div>'
    );
    
    
    var datav = new Ext.DataView({
        autoScroll: true,
        store: catalogoStore,
        tpl: tpl,
        autoHeight: false,
        height: 400,
        multiSelect: true,
        overItemCls: 'x-view-over',
        itemSelector: 'div.thumb-wrap',
        emptyText: 'No images to display',
        style: 'border:1px solid #99BBE8; border-top-width: 0',
    })
    
    
    var buttonsSpecTop = [{
        ui: 'back',
        text: 'Volver',
        handler: function()
            {
                window.open("menu.html","_self");
            }
        },
        {
            xtype: 'spacer'
        }
    ]
    
    
    var dockedItems = [{
        xtype: 'toolbar',
        title: 'Catlogo',
        ui: 'dark',
        dock: 'top',
        items: buttonsSpecTop
    }]
    
    
    catalogoView = Ext.extend(Ext.Panel, 
    {
        fullscreen: true,
        layout: 'card',
            
        initComponent: function() 
        {
            this.crearDocPanel = new Ext.Panel(
            {
                layout: 'card',
                dockedItems: dockedItems,
                items: datav
            });
            
            this.items = this.crearDocPanel;
            catalogoView.superclass.initComponent.call(this);
        }
    });
    
    
    Ext.reg('catalogoView', catalogoView);
    I hope you can help me.
    Thanks in advance.

  2. You need to clean your code up. Your DataView needs to be created within your panel extension but your panel extension has a card layout within a card layout.

    Thanks mitchellsimoens, now my code is like this, but the error still persists:

    Code:
    catalogoView = Ext.extend(Ext.Panel, {
    	fullscreen: true,
    	layout: 'card',
    		
    	initComponent: function() 
    	{
    		this.datav = new Ext.DataView({
    		autoScroll: true,
    		store: catalogoStore,
    		tpl: tpl,
    		autoHeight: true,
    		height: 400,
    		itemSelector: 'div.thumb-wrap',
    		emptyText: 'No hay imgenes para mostrar',
    		style: 'border:1px solid #99BBE8; border-top-width: 0',
    		});
    		
    		this.crearDocPanel = new Ext.Panel(
            {
                dockedItems: dockedItems,
                items: this.datav
    		});
            
            this.items = this.crearDocPanel;
            catalogoView.superclass.initComponent.call(this);
    	}
    });
    What else need to do?
    Thanks.
