ember.js - Injecting application controller into all other controllers -

-

i'm hoping use application controller displaying dynamic modal components. convenient if inject application controller other controllers, rather explicitly injecting in each controller file it's needed. 

initialize = (app) ->     app.inject 'controller', 'appcontroller', 'controller:application'    app.inject 'component' , 'appcontroller', 'controller:application'  injectapplicationcontroller =   name: 'inject-application-controller'   initialize: initialize  `export {initialize}` `export default injectapplicationcontroller`

please forgive coffeescript; gives me error, controller cannot injected other controllers. there workaround?

i recommend use service hold state, can reopen ember.controller in initializer:

ember.controller.reopen({   appcontroller: ember.controller.inject('application') });

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
