I tried to migrate from Rc5 into final version of angular2. I changed module.ts and system.config.js files,also moved all the directives into @ngModule.But now I get following error ,I don't know where is the source of this error? and how can handle it:

message:(what is in browser web console)

Uncaught (in promise): Error: No ErrorHandler. Is platform module (BrowserModule) included?

stack:

"resolvePromise@http://localhost:3002/node_modules/zone.js/dist/zone.js:429:31scheduleResolveOrReject/<@http://localhost:3002/node_modules/zone.js/dist/zone.js:465:17ZoneDelegate.prototype.invokeTask@http://localhost:3002/node_modules/zone.js/dist/zone.js:236:23Zone.prototype.runTask@http://localhost:3002/node_modules/zone.js/dist/zone.js:136:28drainMicroTaskQueue@http://localhost:3002/node_modules/zone.js/dist/zone.js:368:25ZoneTask/this.invoke@http://localhost:3002/node_modules/zone.js/dist/zone.js:308:25"

My problem was because of my module.js. I removed ` // constructor(private _appRef: ApplicationRef) { }

  // ngDoBootstrap() {

  //   this._appRef.bootstrap(SeiApp);

  // }

  // static forRoot(): ModuleWithProviders {

  //   return { ngModule: MaterialRootModule };

  // } `

I had the same error message some time ago. Problem was related to my custom ErrorHandler. Custom ErrorHandler was added in the end of my app.module.ts. You need to move this custom ErrorHandler to the start of this page. I'm using webpack for angular2.
