         id: 'tab_Transfer',
         autoLoad:{url:'/reorder_details',scripts:true}
    }).show();
}

Answer 1

I believe Transfer Stock is a tab panel, and in extjs 4 the tab panel does not have a autoLoad configuration.
Replace the autoload config with a loader

loader: {
        url: '/reorder_details',
        scripts: true,
        autoLoad: true
}
