角度不更新组件

Question

我有一个简单的视图

mapply(function(x, y){cat("x = ", x, " y = ", y, "\n")},
       x = 1:5, y = 1:3)

x =  1  y =  1 
x =  2  y =  2 
x =  3  y =  3 
x =  4  y =  1 
x =  5  y =  2

<div *ngIf = "user$ | async as user "> <app-user-portfolio-edit [user]="user"></app-user-portfolio-edit> </div> 来自

user$

当我调度一个动作并更新this.user$ = this.store.select( state => { const userToEdit = state.user.userToEdit; console.log('selecting user ', userToEdit); return userToEdit; }); 时，我看到userToEdit调用被触发，并且正在返回一个新用户。

但是我的组件没有获得新用户。我有一个属性设置器来侦听更改，该更改在第一次调用后就不会触发。
