We installed our NAV2013R2 NLD Trade+ database – build 35915 and facing issue with the web client.
Error message: Value cannot be null.
Event Viewer says:
Error accessing Website Microsoft Dynamics NAV 2013 R2 Web Client
URL: http://localhost:8080/DynamicsNAV71/WebClient/default.aspx
The ClientExceptionState indicated that the session should be abandoned but the exception handler had no UISession assigned.

Type: System.ArgumentNullException
Message: Value cannot be null.
Parameter name: bindingManager
Generally the issue occurs if we have the Links system part added to the Role Center. Links system part is not supported by Web Client.
If any or one of Role Center’s has the links part added then we can get this error on Web Client.
We deleted the Link part and it started working fine.
