[Vuejs]-<router-view> not funcitoning on upgrade to vue.js 2.0

So the first thing, you dont need to register Vue.component('dashboard', dashboard)
The Reference to in the routes is enough.
Everything else looks good for me. Do you have any Errors in your console?

Try routes = [ { path: '', component ..

It seems like you haven’t registered any component for this action

router.push({
   path: 'details/'+eventId
});

It seems like you need something like that in your router:

 { path: '/details', component: Details }
