angular: enableProdMode, If have any exception, the application will crash (don't re-display data when go to another router)

Hi all, I use angular 2.1.2 and I need to customize ErrorHandler.

“AppModule.ts”:

@Injectable()
class MyErrorHandler implements ErrorHandler {
    handleError(error) {
        console.error("EXCEPTION:", error.message);
        console.error("EXCEPTION:", error.stack);

        setTimeout(() => {
            location.href = "#/error";
            return Observable.of([]);
        });
    }
}

or

@Injectable()
export class MyErrorHandler {
    private appRef;

    constructor(private injector:Injector) {
        setTimeout(() => this.appRef = injector.get(ApplicationRef));
    }

    handleError(exception) {
        this.appRef.tick();
        console.error('EXCEPTION:', exception);
    }
}

When I go to /about page and an error occurs. My app will redirect to /error page. Then I go to /home or another page. The data of this page don’t show on template, just show template without any data. How can I resolve it?
