Angularjs ui-router abstract state with resolve

问题

Is it possible to make an abstract state with ui-router that needs to resolve data? I need to load the top half of a page with profile info, and then have a sub-nav that loads other details at the bottom of the page. The idea is that the abstract state would load the profile info every time regardless of which child state I am on. It doesn't seem to work.

Example:

.state('app.profile', {
    abstract: true,
    url: 'user/:username',
    views: {
        content: {
            templateUrl: 'views/frontend/profile.html',
            controller: 'ProfileCtrl',
            resolve: {
                data: ['$stateParams', 'ProfileService', function ($stateParams, ProfileService) {
                    var username = $stateParams.username;
                    return ProfileService.getProfile(username);
                }]
            }
        }
    }
})
.state('app.profile.something', {
    url: '',
    views: {
        profile: {
            templateUrl: 'views/frontend/profile.something.html',
            controller: 'ProfileCtrl',
            resolve: {
                data: ['$stateParams', 'ProfileService', function ($stateParams, ProfileService) {
                    var username = $stateParams.username;
                    return ProfileService.getProfileSomething(username);
                }]
            }
        }
    }
})

Solution here is to distinguish the names of the resolved data. Check this answer:

angular ui-route state parent and resolve (nested resolves)

And its plunker

So in our case we would need this change in parent

resolve: {
    dataParent: ['$stateParams', 'ProfileService', function ($stateParams, ProfileService) {
        var username = $stateParams.username;
        return ProfileService.getProfile(username);
    }]
}

and this in child

resolve: {
    dataChild: ['$stateParams', 'ProfileService', function ($stateParams, ProfileService) {
        var username = $stateParams.username;
        return ProfileService.getProfileSomething(username);
    }]
}

so, instead of working with resolve : { data: ... } in parent and child we would have these:

// parent state
resolve : { dataParent: ... } 
// child state
resolve : { dataChild: ... }

One working example should be better than other words...
