I’m triggering tick() and detectChanges() in the root component. In root component I have one child with onPush strategy, which logically means it shouldn’t triger that child component if data has not changed.
Really small example about this issue:
https://github.com/michalgrzegorczyk-dev/change-detection
Why ChildWrapperComponent runs ngDoCheck() in this case? It’s OnPush! Why?
NgZone is disabled. The reset of the components works as expected, only root components are triggerend even it’s OnPush.
>Solution :
When you run detectChanges() manually, the component itself and all the children will be checked for changes.
Docs: detectChanges()
Checks this view and its children. Use in combination with detach to
implement local change detection checks.
