ComponentRef Change detector doesn't trigger detecting for view

🐞 bug report

Affected Package

The issue is caused by package @angular/core

Is this a regression?

Cannot say

Description

Component created by #ComponentFactoryResolver. ComponentFactoryResolver#createComponent returns ComponentRef that does have changeDetectorRef.
After any changes to component’s input by code (not by template) and invocation of such ComponentRef#changeDetectorRef.detectChanges component’s view won’t be updated.

example from repro: dynamic-wrapper.component.ts#createComponent.

componentRef.changeDetectorRef.detectChanges()

This is root issue.

To testing purposes ChangeDetectorRef was be added to component’s constructor and invoked by consumer of this ComponentFactoryResolver. CDR from component’s injector works as expected

example from repro: dynamic-wrapper.component.ts#createComponent

componentRef.instance.cdr.detectChanges()

No exception

🌍 Your Environment

Angular Version:

 Angular version 9.1.0

Anything else relevant?

Seems like browser, OS version or anything else doesn’t matter

Workarroud Is to use component’s injector to get Real ChangeDetectorRef.

ComponentRef.injector.get(ChangeDetectorRef)

This was just fixed via #46641 - the ComponentRef has a new method - setInput that correctly sets an input and makes sure that change detection is properly invoked. More details in #46641
