WindowPhone FlipView System.ArgumentException

Question

我在我的WindowsPhone应用程序中使用FlipView有问题。 我有一个页面与FlipView，其中有ItemsSource绑定到ItemsGroup和SelectedItem绑定到CurrentItem。 FlipView的DataTemplate包含WebView，它具有绑定到CurrentItem的Html的属性Html。一切顺利，但应用程序不时崩溃与System.ArgumentException不时，我不知道什么是错的。

XAML：

<Page

<Page.DataContext> 
    <viewModel:PhoneGroupViewModel/> 
</Page.DataContext> 
<Page.Resources> 
    <converter:DateConverter x:Key="DateConverter" 
          IsShowFullDate="True"/> 
</Page.Resources> 
<Grid> 
    <FlipView ItemsSource="{Binding Group.Items}" 
       SelectedItem="{Binding Group.CurrentItem, Mode=TwoWay}"> 
     <FlipView.ItemTemplate> 
      <DataTemplate> 
       <Grid> 
        <Grid.RowDefinitions> 
         <RowDefinition Height="Auto"/> 
         <RowDefinition Height="Auto"/> 
         <RowDefinition/> 
        </Grid.RowDefinitions> 
        <Border Grid.Row="0" 
          Background="{StaticResource ItemBorderBackground}" 
          HorizontalAlignment="Right" 
          Padding="5" 
          CornerRadius="0,0,0,5"> 
         <TextBlock Text="{Binding Published, Converter={StaticResource DateConverter}}"/> 
        </Border> 
        <TextBlock Grid.Row="1" 
           TextWrapping="Wrap" 
           Text="{Binding Title}" 
           FontWeight="Bold" 
           Margin="24,0" 
           FontSize="20" 
           Foreground="{StaticResource LeftMenuBackgroundBrush}"/> 
        <WebView Grid.Row="2" 
          NavigationStarting="WebView_NavigationStarting" 
          common:WebViewBehaviour.Html="{Binding Html}"/> 
       </Grid> 
      </DataTemplate> 
     </FlipView.ItemTemplate> 
    </FlipView> 
</Grid> 

C＃：

public class NewsItem 
    { 
    public string Title { get; set; } 
    public string Link { get; set; } 
    public DateTime Published { get; set; } 
    public string Html { get; set; } 
    public string Image { get; set; } 
    } 

错误：

The parameter is incorrect. System.ArgumentException: Value does not fall within the expected range.

我把它换成默认Templete为FlipView与我自定义的，其中我删除了2.5分边界的边缘。我不知道如何，但它的作品。也许它与指向边缘区域的指针相连，因为从边缘滑动时发生错误。
