Error "ExpressionChangedAfterItHasBeenCheckedError..." when creating items dynamically in Side Navigation #2253

Closed armandorod2000 closed 4 years ago

Is this a bug, enhancement, or feature request?

It seems to be a bug

Briefly describe your proposal.

When building a side navigation and trying to create some list items dynamically, I get the following error:

ERROR Error: ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was checked. Previous value: 'is-selected: undefined'. Current value: 'is-selected: false'.

My understanding is that the attribute "selected" is optional. How do I get around this?

Which versions of Angular and Fundamental Library for Angular are affected? (If this is a feature request, use current version.)

Angular ===> 8.2.13 or 8.3.17 Fundamental library ===> 0.15.1 or 0.15.2

If this is a bug, please provide steps for reproducing it.

I'm writing a very simple example here https://stackblitz.com/edit/angular-mjunz7

Please provide relevant source code if applicable.

In the stackblitz project

Is there anything else we should know?

Hello @armandorod2000, Please consider migrating your project to fundamental-ngx/core@0.16.0, which is also compatible with angular9. There you can test it in angular 9 and ngx@0.16.0: stackblitz
