The WPF Control [Frame]'s Convention doesn't work.

[ipooov]

Hi,
I am studying Caliburn.Micro and meet a question.
I write some code like below in WPF, but it can't work successful:
<Frame x:Name="ActiveItem" NavigationUIVisibility="Hidden" />

ActiveItem is in the view's ViewModel . It bind some Page. And I have already use AddElementConvention method add Frame's convention ,like ContentControl.

I tried to get a answer:
In the method SetContentPropertyCore (in View.cs line 398)

   var contentProperty = type.GetAttributes<ContentPropertyAttribute>(true)
                                          .FirstOrDefault() ?? DefaultContentProperty;

        type.GetProperty(contentProperty.Name)
                    .SetValue(targetLocation, view, null);

here contentProperty.Name is null but contentProperty is not null.

Maybe because Frame has its own ContentPropertyAttribute but has no name :

[ContentProperty]
[DefaultEvent("Navigated")]
[DefaultProperty("Source")]
[Localizability(LocalizationCategory.Ignore)]
[TemplatePart(Name = "PART_FrameCP", Type = typeof(ContentPresenter))]
public class Frame : ContentControl, INavigator, INavigatorImpl, IJournalNavigationScopeHost, INavigatorBase, IDownloader, IJournalState, IAddChild, IUriContext

Please help resolve it and publish in next version, thanks a lot .

Yup, that looks to be the problem (ContentPropertyAttribute with no name).

Thanks for reporting that.

I tried to add Frame's ContentPropertyAttribute Name, And it works well.
