Object reference not set to an instance of an object

[Aura468]

Hello,

One of our users gets the following error:

System.NullRefe renceException: Object reference not set to an instance of an object.

at ***.System.Wind ows.Markup.ISty leConnector.Con nect(Int32 connectionId, Object target)

at System.Windows. FrameworkTempla te.LoadTemplate Xaml(XamlReader templateReader, XamlObjectWrite r currentWriter)

I have already changed the properties of the resources of nested DataTemplates to Dynamic, this has not helped. Maybe there is some other error in the XAML. How can I debug it?

Thanks

This type of error is hard to debug.
From experience, I would check to make sure that the resource names Properly Match (it's so easy to miss a typeo)
