Events not triggered correctly when using connect mixin

By emacsen at Stack Overflow: http://stackoverflow.com/questions/28179086/not-triggering-react-event-correctly.

Store

var taskStore = Reflux.createStore({
  listenables: [taskActions],
  init: function(){
    this.tasks = [];
    this.index = {};
    this.trigger(this.tasks);
  },
  onLoad: function(arr){
    var idx = {}
    arr.forEach(function(ele){
      idx[ele.id] = ele
    });
    this.tasks = arr;
    this.index = idx;
    this.trigger(arr);
  }
});

Component

var App = React.createClass({
    mixins: [
        Reflux.connect(taskStore,"tasks"),
        Reflux.connect(taskIndex, "index"),
    ],
...

Causes a Uncaught TypeError: Cannot read property 'apply' of undefined in Chrome, originating from the listen method.

  componentWillMount: function(){

    // Assign listeners for data loading
    this.listenTo(ChatterStore, this.publishedDataStatus);
  },

where publishedDataStatus was not anywhere in my code yet.
