Make a CompositeView with NextCollectionView

NextCompositeView.js

var MixinFromView = _.pick(Marionette.View.prototype, 'serializeModel', 'getTemplate', '_renderTemplate', 'mixinTemplateContext', 'attachElContent');

var NextCompositeView = Marionette.NextCollectionView.extend({
  childView: function() {
    return this.constructor;
  },
  serializeData: function() {
    return this.serializeModel();
  },
  getChildViewContainer: function() {
    var selector = _.result(this, 'childViewContainer');
    
    return selector ? this.findEls(selector, this.$el) : this.$el;
  },
  onBeforeRender: function() {
    this._renderTemplate();
    this.bindUIElements();
    this.$childViewContainer = this.getChildViewContainer();   
  },
  attachHtml: function(collectionView, els) {
    this.appendChildren(this.$childViewContainer, els);
  }
});

_.extend(NextCompositeView.prototype, MixinFromView);
