ember.js - "Resolved all models on destination route, finalizing transition". But Ember renders 'view:loading' -

router calls hooks hangs in finalizing transition renders view:loading.

the problem is, don't know why ember isn't finalizing transition, far know models:menus fetched , categories sideloaded.

both categories , categories.index routes defined. categories , categories:index controllers defined , ember.arraycontroller.extend({})

categoriesroute

export default ember.route.extend({   model: function(params){     return this.modelfor('menus').findby('id', params.menu_id).get('categories');   } }); 

categoriesindexroute

export default ember.route.extend({   model: function(params){     return this.modelfor('categories');   } }); 

what ember logs:

due lack of template controller, ember hangs in finalizing transition since can't render template.

i'm not 100% sure though, apparently of mar 2014 ember app kit grunt server task isn't compiling new files.
