I have a method handleError() like in the documentation https://angular.io/docs/ts/latest/guide/server-communication.html#!#error-handling

private handleErro         


        

Answer 1

this in handleError in your case is probably not what you think it is.

Try to do the following:

this.http.get(url,
              ApiRequest.ACCEPT_JSON)
              .map(ApiHelper.extractData) 
              .catch(this.handleError.bind(this)); // <-- add .bind(this)
