Hi, I'm creating an app for SL5 (VS2010), and after getting several groupboxs on a page, I now get the following error as soon as I add the child control (StackPanel) to the groupbox:
NullReferenceException was thrown on GroupBox34343: [Line:0 Position:0]
Object reference not set to an instance of an object.
at System.Windows.FrameworkElement.OnApplyTemplate(IntPtr nativeTarget)
Anyone seen this error? Thanks for any suggestions.
