@AdiShuk you are using angular-rollup which is great, but you should file the bug in that repo. This is not an issue with closure or the closure-demo, but that repository. File an issue or login to the gitter channel and I will help you get started with the repo. This is most likely a support request. https://github.com/steveblue/angular2-rollup/issues

Thanks. Will follow up over there if I am not able to resolve the issue on my own. Apologies.
