App = Ember.Application.create();

App.DummyView = Ember.View.extend({
  templateName: 'dummy',
  val: 'cocorico'
});

App.IndexController = Ember.ArrayController.extend({
  model: [{t: '1'}, {t: '2'}],
  viewName: 'dummy',
  viewClass: App.DummyView
});

{{each itemView='dummy'}} works, but before it used to work with dynamic view class or name,and now that do not work anymore:

• {{each itemView='dummy'}} => OK
• {{each itemView=viewName}} => broken
• {{each itemView=viewClass}} => broken
• the 2 last ones with itemViewClass instead of itemView do not work as well

I don;t remember how it used to work, but it used to work with at least one of the 4 not working above
