javascript - Emberjs - Controller always gets default value from 'needs' controller -


i have situation have application controller 'needs' access property controller, this:

app.applicationcontroller = ember.controller.extend({     needs: ['sort'],      actions: {         appclicked: function () {             console.log('controllers.sort.ismenuexpanded');         }     } });  app.sortcontroller = ember.controller.extend({     ismenuexpanded: false,      actions: {         menuclicked: function () {             this.toggleproperty('ismenuexpanded');         }     } })

as expected, applicationcontroller's appclicked function correctly logs 'false' first time run. however, continues logging false (the default value set in sortcontroller) after ismenuexpanded property has been changed 'true' sortcontroller.

this may have way javascript passes values. think objects passed reference, , sure enough, if change ismenuexpanded property to:

ismenuexpanded: { expanded: false }

and change toggle to:

this.toggleproperty('ismenuexpanded.expanded');

the action in applicationcontroller correctly prints ismenuexpanded.expanded value console every time it's updated.

thanks in advance time , expertise!

try setting computed property.

app.applicationcontroller = ember.controller.extend({     needs: ['sort'],     ismenuexpanded: ember.computed.alias('controllers.sort.ismenuexpanded'),      actions: {         appclicked: function () {             console.log(this.get('ismenuexpanded'));         }     } });  app.sortcontroller = ember.controller.extend({     ismenuexpanded: false,      actions: {         menuclicked: function () {             this.toggleproperty('ismenuexpanded');         }     } })
