Does any one met the issue of angular 7 cdk virtual scrolling working abnormally in mat-tab group.



https://github.com/angular/material2/issues/13981



My city component template looks like that



<cdk-virtual-scroll-viewport class="list-container" [itemSize]="50" minBufferPx="200" maxBufferPx="400" (scrolledIndexChange)="getNextBatch($event)">

  <div *cdkVirtualFor="let state of statesObservable | async; trackBy: trackByFn" class="list-group-item state-item">

    <div class="state">{{state.name}}</div>

    <div class="capital">{{state.capital}}</div>

  </div>

</cdk-virtual-scroll-viewport>


When put this city component to the mat-tab-group as the second tab 



<mat-tab-group>

  <mat-tab label="Country">

    <app-country></app-country>

  </mat-tab>

  <mat-tab label="City">

    <app-city></app-city>

  </mat-tab>

</mat-tab-group>


The result looks like belenter image description hereow:

          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...
