layoutHeader is defined by autoref

MyViewport = Ext.extend(MyViewportUi, {
initComponent: function() {
MyViewport.superclass.initComponent.call(this);
this.layoutHeader.on('render', this.onLayoutHeaderRender, this);
},
onLayoutHeaderRender:function(cm){
Ext.apply(cm,{contentEl:'my-div'});
}
});

cheers
