Conflict with Prototype.js

[rainbow99984]

I'm trying to use this with app which use prototype.js and get following error:

TypeError: (intermediate value).observesBefore is not a function
    ...is.notifyPropertyChange("cellContent")},contentPathWillChange:function(){var a;r...
    ember-table.min.js (line 6, col 20708)

Error: <(subclass of Ember.View):ember326> Handlebars error: Could not find property 'table-component' on object <App.IndexController:ember337>.

I've used :
 window.ENV = {};
     ENV.EXTEND_PROTOTYPES = false;

as suggested in Ember.js as suggestion for conflict. If I remove the ember-table Ember.js works fine.
to make it appear just use prototype.js in app page.
Thanks
