It breaks when moving from (Plnkr):
.state('home', {url: '/home', template: '<pre>{{parentProp}}</pre>',
controller: function ($scope) {$scope.parentProp = ['home'];}})
To (Plnkr):
.state('home', {url: '/home', views: {'': {template: '<pre>{{parentProp}}</pre>'}},
controller: function ($scope) {$scope.parentProp = ['home'];}})`
Specifically I have a 'sidebar'
state I want to add as a secondary state to 'home'
.
