Object reference not set to an instance of an object

Hello,

One of our users gets the following error:

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

at ***.System.Windows.Markup.IStyleConnector.Connect( Int32 connectionId, Object target)

at System.Windows.FrameworkTemplate.LoadTemplateXaml( XamlReader templateReader, XamlObjectWriter 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)
