I have Angular 2 (beta.6) installed using JSPM. When I then start my app I get the message of 'reflect-metadata' being required (see also Angular2 + Jspm.io : reflect-metadata shim is required when using class decorators). Installing this also via JSPM solves the issue.
But then I stumble on the next problem. The ngFor is not giving me the expected behavior. When I add records to a list of a component, it doesn't get updated. I tried adding them via click-event handlers and setTimeout, etc. but it doesn't seem to trigger the so called 'application tick'.
