my container has following code 

ext.define('wl.view.tablet.container2', {      extend: 'ext.container',     xtype: 'tabletcontainer2',      config: {          layout: 'card',          items: [             {                 xtype: 'merchants',                 docked: 'left',                 width: 320,                 style: 'border-right: 2px solid #000'             },             {                 xtype: 'container',                 cls: 'tabletsplash',                 flex: 1             }         ]     } });

i want show list of merchants products along side merchants list when of merchants in list tapped, 2 lists displayed side side

i tried use following code achieve 

    var products = ext.widget('products');     ext.widget('tabletcontainer').setactiveitem(products);

but isn't working expected me , ideas on how set active item inside container?
