and of course controller:

ext.define('caltable.controller.thecontroller', {     extend: 'ext.app.controller',     requires: ['ext.util.history'],      refs: {         contentpanel: '#contentpanel',         menu: '#menu',         menupanel: '#menupanel'     },      onlaunch: function () {         ext.history.init();         ext.history.on('change', this.navigate, this);         this.navigate(window.location.hash);     },      navigate: function (id) {         if (id) {             if (id[0] == '#') id = id.slice(1);             this.getcontentpanel().layout.setactiveitem(id + 'panel');             this.getmenu().items.each(function (item) {                 if (item.href == '#' + id) {                     item.disable();                     window.document.title = item.text;                 }                 else {                     item.enable();                 }             });         }     } });

the error caused in line:

this.getcontentpanel().layout.setactiveitem(id + 'panel');

because underlying issue ids of menu items , cards have match.

you have menu items

home foliolist calendar

but ids have in card layout are

homepanel foliopanel calendarpanel

so when menu item id foliolist clicked , subsequently setactiveitem("foliolistpanel") executed, no item id foliolistpanel exists, obscure error thrown in extjs.

while changing id should fix problem @ hand, want amend controller check whether item exists before navigating, because navigation can executed through user-changed anchor, , don't want user break app way.
