Angular2 beta 15 Tour of Heros sample does not working on EB1.4

Hi,

 

Angular2 beta 15 (Typescript) Tour of Heros sample does not working on EB1.4. Regardless if i compile against es5 or 6.

 

Error Message from Web Inspector INVALID_STATE_ERR: DOM Exception 11: An attempt was made to use an object that is not, or is no longer, usable. :3000/javascript/angular2-polyfills.js:1000

 

Firefox,Chrome and yes, even Internet Explorer shows the site without Errors if i compile typescript against es5.

 

So whats the matter?
