I am not familiar at all with Silverlight but have to fix an issue with a program that if a user clicks on a particular tab on the screen they get the following error:
Error: Unhandled Error in Silverlight Application
Message: System.NullReferenceException: Object reference not set to an instance of an object.
at xx.URP.Presentation.Silverlight.URPServices.Actions.MonitorResult.Equals(Object obj)
at System.Windows.Controls.ContentControl.OnContentChanged(IntPtr nativeTarget, CValue& oldContentValue, CValue& newContentValue)
The code does not break within Visual Studio during this error. Instead I get a window in IE that shows me this error. Anyone have any ideas as to what the problem could be? Browser is IE8, using VS 2010 and Silverlight 3.
