Question

您好我目前在我的{N}项目中使用nativescript-telerik-ui插件并使用如下所示的RadListView

<RadListView #myRadListView [items]="posts"
             loadOnDemandMode="Auto" (loadMoreDataRequested)="onLoadMoreItemsRequested($event)"
             itemDeleteAnimation="Fade" [listViewLayout]="layout">
    <template tkListItemTemplate let-post="item" let-index="index">
        <!--- data goes here -->
    </template>
    <template tkListViewHeader>
      <Label text="next page" [nsRouterLink]="['/next-page']"></Label>
    </template>
</RadListView>

在NextPage组件中，当用户点击后退按钮ActionItem时，我将页面重定向到帖子页面（即RadListView页面），如下所示

goBack(){
        this.routerExtensions.backToPreviousPage();
    }

当loadOnDemandMode＆＃39;没有触发，即列表中加载了初始项目。当使用loadOnDemandMode刷新列表并使用backToPreviousPage（）点击下一页并从该页面返回时，我收到以下错误

Nativescript angular 2 RadListView LoadOnDemand返回上一页不起作用（评估＆＃39; child.onLoaded＆＃39;）
