[0.0.9-rc.1] Array changes event is not delivered

[ragingwind]

I've testing in 0.9.0-rc.1. I couldn't get events from a changed of array by Array mutation API. It seems that 'users-changed' event is not bind to the node. I confirmed that node.dispatchEvent is called but userAddedOrRemoved is never called until I binded users-changed event to the node in manually for testing. here is my test code and logs.

Polymer({
  is: 'x-custom',

  properties: {
    users: {
      type: Array,
      value: []
    }
  },

  observers: [
    'usersAddedOrRemoved(users.splices)'
  ],

  usersAddedOrRemoved: function(changeRecord) {
    console.log('usersAddedOrRemoved', changeRecord);
  },

  addUser: function(user) {
    this.push('users', user);
  },

  removeUser: function(user) {
    var index = this.users.indexOf(user);
    this.splice('users', index, 1);
  }
});

var xs = document.querySelector('x-custom');

// usersAddedOrRemoved is not fired
xs.addUser('John');
xs.removeUser('John');
xs.fire('users.splices');
xs.fire('users.changed');

// usersAddedOrRemoved is fired
xs.addEventListener('users-changed', xs.usersAddedOrRemoved);
xs.addUser('John');
xs.removeUser('John');

Still exist in 0.9. The test code something went wrong?

Hi -- I'm not seeing this issue when I put your code in jsbin:

I am seeing an extra call to usersAddedorRemoved (perhaps that represents the empty state). But it seems to work...

Sorry for bothering you. I works well with 0.9 after reinstalling
