Same case for me while trying to build a todoApp.

I ran into the same issue.

That's probably because an error in a View's directives, there is a PR pending on angular.
see angular/angular#1917

Closed. Obsolete.

@wardbell this should be reopened. The error is an uncaught exception that occurs in several situations. For me, it occurs when a route is defined without a component declaration. The main issue is that the error message is useless and difficult to trace. In my case, it indirectly results from the resolve.ts code:

_ => resolver.resolveComponent(<any>node.value.component).then(factory => { node.value._resolvedComponentFactory = factory;

which cascades as an error in a wholly different call stack. The assignment above should be guarded by checking for a factory value and issuing the appropriate error. In addition, the route should be validated beforehand. Furthermore, there should be a separate task to ensure that the (forthcoming?) route documentation specifically states what is required.

This issue and its response are symptomatic of a pervasive cavalier disregard for defensive programming in the Angular development process. I appreciate how developers under pressure let issues like this slide, but technical leads and QA should know better. Code review, anyone? Unfortunately, defensive programming must be integral to the development process and is difficult to address after initial functional goals are achieved.

@FredLoney the issue you are referring to should be reported in https://github.com/angular/angular rather than in the quickstart.

The quickstart repo aims to provide a barebones development environment and is not the place to report issues with Angular 2 itself.

Oops, I thought all Angular modules shared a common issues list.
