Vue-material: [MdSnackbar] Uncaught TypeError: Cannot read property '_vnode' of undefined

[dakshshah96]

Steps to reproduce

<template>
  <md-content>
    <form @submit="submitForm">...</form>
    <md-snackbar md-position="center" :md-active.sync="loginMessage.status">
      <span>{{loginMessage.message}}</span>
    </md-snackbar>
  </md-content>
</template>
<script>
export default {
  name: 'login',
  data: () => ({
    loginMessage: {
      active: false,
      message: ''
    }
  }),
  methods: {
    submitForm () {
      this.loginMessage = { status: true, message: 'Please wait while we log you in...' }
      this.$store.dispatch('login', {
        phoneNumber: this.loginForm.phoneNumber,
        password: this.loginForm.password
      })
        .then((res) => {
          console.log(res)
          this.loginMessage = { status: true, message: 'Login successful!' }
          this.$router.replace('/dashboard')
        })
        .catch((err) => {
          console.error(err) 
        })
    }
  }
}
</script>

The 'Please wait while we log you in...' snackbar is displayed without any errors. Once login is successful, it is replaced with the 'Login successful!' text and user is redirected to the /dashboard page.

After getting redirected to /dashboard, the following error is printed in my console after 2-3 seconds:

Uncaught TypeError: Cannot read property '_vnode' of undefined

@dakshshah96 would you try it with dev branch?

[darkoromanov]

Sorry for the dummy question but how do I select the dev branch from npm? I have the same issue using 1.0.0-beta-10.2

Nevermind, googled for it but still have the same issue.

this still exists.

Below is the cause for the bug. A simple fix is to call createPromise with correct arguments.

The bug:
In md-snackbar implementation, a call tocreatePromise() is made with an incorrect number and order of arguments.
The function createPromise(duration, persistent, context) is called ascreatePromise(duration, context).
So context within createPromise() is undefined and that causes an exception in context._vnode.componentInstance.initDestroy(true);

A snippet:
```var createSnackbar = exports.createSnackbar = function createSnackbar(duration, context) {
if (currentSnackbar) {
return destroySnackbar().then(function () {
return createPromise(duration, context);
});
}

return createPromise(duration, context);
};

function createPromise(duration, persistent, context) {
```
