PathGeometry doesn't render when references a resource

In WPF both examples render fine, but in NoesisGUI (with Unreal), the last one produces:

Cannot convert 'M 1888.2001 1.915677 V 1001.9211 l -24.8263 43.0005 h -392.9762 l -65.2936 29.7968 h 486.7515 L 1920 1025.9707 V 1.915677 Z' into a 'PathFigureCollection' object

Settings Figures directly:

<Path Fill="White" StrokeThickness="0.264583">
    <Path.Data>
        <PathGeometry Figures="M 1888.2001 1.915677 V 1001.9211 l -24.8263 43.0005 h -392.9762 l -65.2936 29.7968 h 486.7515 L 1920 1025.9707 V 1.915677 Z" FillRule="NonZero"/>
    </Path.Data>
</Path>

Setting Figures through a resource:

<ResourceDictionary>
    <PathFigureCollection x:Key="Path.FrameRight">
        M 1888.2001 1.915677 V 1001.9211 l -24.8263 43.0005 h -392.9762 l -65.2936 29.7968 h 486.7515 L 1920 1025.9707 V 1.915677 Z
    </PathFigureCollection>
</ResourceDictionary>

<Path Fill="White" StrokeThickness="0.264583">
    <Path.Data>
        <PathGeometry Figures="{StaticResource Path.FrameRight}" FillRule="NonZero"/>
    </Path.Data>
</Path>

I was able to fix it by declaring a Geometry instead and using it directly as Data

<Geometry x:Key="Path.FrameLeft">...</Geometry>
...
<Path Data="{StaticResource Path.FrameLeft}" ... />

Not sure what UWP has to do with NoesisGUI

We are clearly missing a converter in Noesis to support this scenario. Could you please report it in our bugtracker.

Yes, that is what we recommend to reuse geometries.

By the way, the account above seems to be a spam bot.

Thanks for the report, we'll implement it soon.
