Error Code 4004

[TanyaOwens]

I get the following error when I try to use the navigation tool:

An unhandled exception ('Unhandled Error in Silverlight application)
Code: 4004
Category: ManagedRuntimeError
Message: System.NullReferenceException: Object reference not set to an instance of an object.


Any suggestions?

Have you confirmed that the Map property on the Navigation tool is set correctly?

[TanyaOwens]

Your right - I forgot to add Map ="{Binding ElementName=MyMap}". I guess that is important. 😮 Thanks for your help.

Hi folks,

I encountered a similar issue which I started to run the Silverlight Application, it always shows somehow a security issue and feature layer info issue message, please take look at the attached screen shot, if you have any ideas to fix the problem, thank you in advance.
