I have an angular 6 application. I am trying to load users from a backend. Here is my component typescript part:



 this.users$ = this.userSearchControl

  .valueChanges

  .debounceTime(200)

  .filter(q => q && q.length > 5)

  .switchMap(q => this.getUsers(q))

  .share();


And template part:



<div *ngIf="(users$ | async) as users" class="results">



  <ul class="list">

    <li *ngIf="users.length===0">

      <div class="no-results">

        <span>No orders found</span>

      </div>

    </li>

    <li *ngFor="let user of users" class="list-item">

      {{user.Name}}

    </li>

  </ul>

</div>


And I am getting an exception:




ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was checked. Previous value: 'ngIf: false'. Current value: 'ngIf: true'.




I have tried to play around ChangeTracker, and delay(0) but no success. Thanks for any assistance

          Run scheduled task as local user group (not BUILTIN)

          Image
          0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers? scheduled-tasks taskscheduler windowstaskschedule share | improve this question asked Nov 15 '18 at 15:36 Far...
