ember.js - why am i seeing "error while loading route" with ember? -

Amber RC1, Amber-Data Amendment 12. All my routes are loading correctly, unsure why I I am seeing this error when I try to use the show route ie. Corrected / files / groups / 5 index paths

I have pasted the stack trace below but it is not very informative

  this.resource ('files', {path: 'i / Files'}, function () {this.resource ( 'groups', {path: '/ groups'}, function () {this.route ( 'show', {path: '/: asset_link_group_id'});});}); AssetLinksApp.GroupsShowController = Ember.ArrayController.extend ({content: Ember.A (), assetLinkGroup: null}); AssetLinksApp.GroupsShowRoute = AssetLinksApp.AuthRequiredRoute.extend ({setupController: function (controller model) {controller.set ( 'content', model.get ( 'asset_links')); controller.set ( 'assetLinkGroup', model);} , Model: Functions (Parameters) {Return Assetlinks App. Asset Link Group. FIDD (Params.asset_link_great_id_id);}});   
 Stack trace:

 The model returns a single record even though you have defined the  ArrayController .  
 Ember.js automatically keeps the model in the property of the controller's content, causing the error to occur because it will maintain a record in an array of controllers.  
 Although you override the  setupController , before it fires, amber.js will place the model in the controller anyway. Currently there is no way of stopping  
 
 update 3-Jun-2014 (amber> 1.0) :.  
 Now the override then  setupController  amber no longer sets the property  model .  
 
 The only solution I can think is to add resources to our routes:  
  This.resource ('files', {path:' / files'}, function () {this.resource ( 'groups', {path:' / groups'}, function () {this.resource ( 'group', {Path: '/: asset_link_group_id'}, function () {This.route ('index');});});});   
 This means that you have an object controller ( GroupController ) group containing, and code an array controller (<> GroupIndexController ) with each link Array    AssetLinksApp.GroupIndexController = Ember.ArrayController.extend ({assetLinkGroup: null}); AssetLinksApp.GroupIndexRoute = AssetLinksApp.AuthRequiredRoute.extend ({setupController: function (controller model) {Niyntrkkset ( 'content' model); Niyntrkkset ( 'AssetLinkGroup, ThiskmodelFor (' Group '));} , Model: functions (parameters) {return.modelfor ('group'). Get ('asset_links');}});   
 Your template should now be named  group / index  instead of  groups / show . For the  group  template, this can be an empty template containing  {{outlet}} .  
 This is worth noting that the most important thing: If your controller is an object controller, model hook object  back , and if your controller array controller, you  to return an array of model  hook.  
 The bright side, it is better that pushes you to follow a certain design I might think of the core team.
