using extjs 4.2 mvc pattern

i trying make custom model, store, proxy, reader, writer having problems getting work in mvc pattern. followed this example extend model , can see working if not used in mvc way.

my store refers model such contacts defined in model property, contacts refers custom model wakandamodel using model property. when create store refers contacts none of model properties or proxy defined in custom wakandamodel brought on stores model.

here code, have left comments in can see have attempted try. help!

app code

ext.loader.setconfig({     enabled : true,     paths   : {         'ext.ux'    : "lib/extux",         'wakanda'   : "lib/extux/wakanda"     } }); ext.application({     name : 'simplyfundraising',     autocreateviewport : true,      requires : ['ext.ux.router', // require ux     'ext.window.messagebox'],      controllers : ['contacts'], }); 

custom model

ext.define('wakanda.model', {      extend: 'ext.data.model',      idproperty: '__key',      stampproperty: '__stamp',      defaultproxytype: 'wakanda',      onclassextended: function(cls, data) {           //    debugger;        // cls.apply(this) //        var parts = data.$classname.split('.'); //        var entity = parts[2] //        var catalog = this.prototype.getcatalog(entity), //            attributes = catalog.attributes; //        (var = 0, l = attributes.length; < l; i++) { //            if (attributes[i].name === 'id') { //                attributes[i].persist = false; //            } //        } //        attributes.push({name: this.prototype.idproperty}); //        attributes.push({name: this.prototype.stampproperty}); //       // data.fields = attributes; //      //  debugger; //        //this.setfields(data.fields) //      // var mymodel = ext.modelmanager.getmodel(data.$classname);      //   debugger;        // ext.appy(this); //        //this.superclass.superclass.$onextended.apply(this, arguments);     },      getcatalog: function(classname) {         var catalog;         ext.ajax.request({             async: false,             url: 'http://127.0.0.1:8081/cors/$catalog/' + classname,             success: function(response) {                 catalog = ext.decode(response.responsetext);             }         });         return catalog;     }  });

i got working now:

it looks custom wakanda model,proxy,reader,writer not loading. still bit confused on how mvc references classes , loads files , instantiates classes, asked in other question.

any way fix add requires custom wakanda model , proxy

for wakanda model add requires: ['wakanda.proxy'],
wakanda proxy add requires: ['wakanda.reader', 'wakanda.writer'],

now inheritance working expected.
