嗨目前我在我的项目中使用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'未被触发，即列表中加载了初始项时，它工作正常 . 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
