Angular exception: Can't bind to 'ngForIn' since it isn't a known native property

Question

What am I doing wrong?

import {bootstrap, Component} from \'angular2/angular2\'

@Component({
  selector: \'conf-talks         


        

Answer 1

Simply replace:

with

So, you must replace in with of inside ngFor directive to get the values.
