Javascript – Vue router programmatic navigation not works

My programmatic navigation in the component using the vue-router is not working. After the successfull login I want redirect it to the dashboard page. But nothing happens…

Relevant code – the router:

import Vue from 'vue'
import Router from 'vue-router'
import store from '../store'
import Login from '@/components/Login'
import Dashboard from '@/components/Dashboard'

Vue.use(Router)

export default new Router({
  mode: 'history',
  routes: [
    {
      path: '/login',
      name: 'login',
      component: Login,
      beforeEnter: (to, from, next) => {
        if (store.getters.isAuthenticated) {
          // if user is already authenticated,
          // redirect it to the dashboard
          next('/dashboard') // it works
        } else {
          next()
        }
      }
    },
    {
      path: '/dashboard',
      name: 'dashboard',
      component: Dashboard,
      beforeEnter: (to, from, next) => {
        if (store.getters.isAuthenticated) {
          next()
        } else {
          // if user is not authenticated,
          // redirect it to the login
          next('/login') // it works
        }
      }
    }
  ]
})

Method in component:

userLogin () {
  this.authorizeUser({
    name: this.user.name,
    pass: this.user.pass
  }).then(result => {
    console.log('redirected to dashboard')
    this.$router.push('dashboard') // this doesn't work
  })
}

No errors there, but no action is taken also – I'm still staying on the login page. What am I missing?

EDIT:

This works: this.$router.go('dashboard') Does it mean I'm using the old version?
