angularJS ui-router url变化，但模板不渲染

Question

url变成'account/signin'，有请求模板 account.html和signin.html，但是没有渲染

index.html

<div ui-view="main">
</div>

app/account/account.html

<div ui-view="form">
</div>

app.js

$stateProvider
        .state('account', {
            url: '/account',
            abstract: true,
            views: {
                'main@': {
                    templateUrl: 'app/account/account.html',
                    controller: ['$state', function ($state) {
                        console.log('account');
                        $state.go('account.signin');
                    }]
                }
            }
        })
        .state('account.signin', {
            url: '/signin',
            views: {
                'form@account': {
                    templateUrl: 'app/account/signin.html',
                    controller: ['$state', function ($state) {
                        console.log('sign in ');
                    }]
                }
            }
        })

控制台会打印 'account',但不打印 'sign in'

补充：没有改变代码，刚刚测试，不打印 'account'

Answer 1

<div ui-view="form" name="form@account">
</div>
可以吗
