Attempt to use a destroyed view: detectChanges

Question

I am creating a simple UI using Angular Meteor 2.

1) I have a top navbar component which has a 'logout' button.
2) On clicking 'logout' button it redirects to 'login'.
3) Then I see this error in console : EXCEPTION: Attempt to use a destroyed view: detectChanges

Exception:

Answer 1

Only solution that worked for me was:

if (!this.changeDetectionRef['destroyed']) {     this.changeDetectionRef.detectChanges(); }
