using_childViews_after_1.13.md

In 1.13.0-beta.1 and above, the childViews array is not maintained (HTMLBars maintains a tree structure instead of a flat array listing).

I spiked getting things working for both pre-1.13 and post in this JSBin, snippet below:

  didRender: function() { 
    function filterAttrMorphs(node) {
      return node.constructor.name !== 'AttrMorph';
    }
    var childViews = this._renderNode.childNodes.filter(filterAttrMorphs)[0].childNodes
    .map(function(node) {
      return node.emberView;
    });

    this.set('childViews', Ember.A(childViews));
  }
