How do I show multiple views in an abstract state template?

Question

Using Angularjs UI-Router I'm trying to build a typical page with a main view and a side refine/filter results view.

I've forked the sample app and now modifying it to have a parent abstract state that displays the filters view and the main view so that I can share the data that the abstract state resolves.

The problem is I cannot get the filters view to appear without breaking the scope inheritance. If I add the 'views' param it breaks the scope so how can I get this to work?

Here's my code and Plunker

$stateProvider
  .state('applications', {
      abstract: true,
      url: '/applications',
      templateUrl: 'planning.html',
      controller: function($scope){
          $scope.planning = [{ id:0, name: "Alice" }, { id:1, name: "Bob" }];

          $scope.filterPlanning = function(data) {
            var output = $scope.planning;
            // test filter
            output = $filter('filter')({ name: "Alice" });
            return output;
          }
      },
       /* this breaks the scope from being inherited by the child views
      views: {
          '': {
            templateUrl: 'applications.html'
          },
          'filters@applications': {
            templateUrl: 'applications.filters.html'
          }
      },*/
      onEnter: function(){
        console.log("enter applications");
      }
  })

child states:

  .state('applications.list', {
      url: '/list',
      // loaded into ui-view of parent's template
      templateUrl: 'planning.list.html',
      onEnter: function(){
        console.log("enter applications.list");
      }
  })
  .state('applications.map', {
      url: '/map',
      // loaded into ui-view of parent's template
      templateUrl: 'planning.map.html',
      onEnter: function(){
        console.log("enter applications.map");
      }
  })

applications.html

<div class="row">
  <div class="span4">
    <div ui-view="filters"></div>
  </div>
  <div class="span8">
    <div ui-view></div>
  </div>
</div>

I already have the list, map and filters views built as directives so I'm hoping once I can get this demo working I can swap them in relatively easily.

There is updated plunker

I would say, that the issue here is:

Any controller belongs to view not to state

so this is the adjusted code:

.state('applications', {
    abstract: true,
    url: '/applications',
    // templateUrl and controller here are SKIPPED
    // not used
    // templateUrl: 'applications.html',
    // controller: ...
    views: {
      '': { 
        templateUrl: 'applications.html',
        controller: function($scope, $filter){
            $scope.planning = [
              { id:0, name: "Alice" }, 
              { id:1, name: "Bob" }
            ];

            $scope.filterPlanning = function(data) {
              var output = $scope.planning;
              // test filter
              output = $filter('filter')({ name: "Alice" });
              return output;
            }
        },
      },
      'filters@applications': {
        templateUrl: 'applications.filters.html'
      }
    },

Check the doc:

Views override state's template properties

If you define a views object, your state's templateUrl, template and templateProvider will be ignored. So in the case that you need a parent layout of these views, you can define an abstract state that contains a template, and a child state under the layout state that contains the 'views' object.

The plunker to check it in action
