Question

我的WP8-App使用Xamarin和MvvmCross运行。

当我打开我的应用程序正常然后通过设备上的开始按钮/窗口按钮返回并尝试通过应用程序列表重新打开我的应用程序时，我的应用程序崩溃，出现以下异常：

{Cirrious.CrossCore.Exceptions.MvxException: Unable to find incoming MvxViewModelRequest
   at Cirrious.MvvmCross.WindowsPhone.Views.MvxPhoneViewsContainer.GetRequestFromXamlUri(Uri viewUri)
   at Cirrious.MvvmCross.WindowsPhone.Views.MvxPhoneExtensionMethods.LoadViewModel(IMvxPhoneView phoneView, Uri navigationUri, IMvxBundle savedStateBundle)
   at Cirrious.MvvmCross.WindowsPhone.Views.MvxPhoneExtensionMethods.<>c__DisplayClass1.<OnViewCreate>b__0()
   at Cirrious.MvvmCross.Views.MvxViewExtensionMethods.OnViewCreate(IMvxView view, Func`1 viewModelLoader)
   at Cirrious.MvvmCross.WindowsPhone.Views.MvxPhoneExtensionMethods.OnViewCreate(IMvxPhoneView phoneView, Uri navigationUri, IMvxBundle savedStateBundle)
   at Cirrious.MvvmCross.WindowsPhone.Views.MvxPhonePage.OnNavigatedTo(NavigationEventArgs e)
   at MyApp.MyNamespace.Views.BasePage.OnNavigatedTo(NavigationEventArgs e)
   at Microsoft.Phone.Controls.PhoneApplicationPage.InternalOnNavigatedTo(NavigationEventArgs e)
   at Microsoft.Phone.Controls.PhoneApplicationPage.Microsoft.Phone.Controls.IPhoneApplicationPage.InternalOnNavigatedToX(NavigationEventArgs e)
   at System.Windows.Navigation.NavigationService.RaiseNavigated(Object content, Uri uri, NavigationMode mode, Boolean isNavigationInitiator, IPhoneApplicationPage existingContentPage, IPhoneApplicationPage newContentPage)
   at System.Windows.Navigation.NavigationService.CompleteNavigation(DependencyObject content, NavigationMode mode)
   at System.Windows.Navigation.NavigationService.ContentLoader_BeginLoad_Callback(IAsyncResult result)}

这发生在每个页面上（也就是显示一些文本的静态页面）。

当我尝试通过“last-opened-app”列表重新加载我的应用程序时（长按我设备上的后退按钮）一切正常，显示最后一页并且不会发生异常。

如果您需要更多信息，请提出要求。谢谢
