Subject RE: Installation problem with Log4Net Dashboard 1.2: Object reference not set to an instance of an object.

Hi Christoph,

 

Have you checked that the web server (IIS) has session handling enabled?

 

Best regards

not set to an instance of an object. 

 


Dear mailing list, 

I'm getting into troubles installing Log4Net Dashboard 1.2 on a Windows 2003
server that runs IIS 6.0 with .NET v1.1.4322. 

After installing the software using the installation files from
http://www.l4ndash.com/Download/tabid/53/Default.aspx, the URL
http://localhost/l4ndash returns the following error: 

Server Error in '/L4NDash' Application. 
----------------------------------------------------------------------------
---- 

Object reference not set to an instance of an object. 
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code. 

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

Source Error: 

An unhandled exception was generated during the execution of the current web
request. Information regarding the origin and location of the exception can
be identified using the exception stack trace below.   

Stack Trace: 

[NullReferenceException: Object reference not set to an instance of an
object.] 
   FNFrmw.FNSessionData.GetSession() +22 
   L4NDash.State.SessionData.GetSession() +5

   System.Web.UI.Control.LoadRecursive() +98 
   System.Web.UI.Control.LoadRecursive() +98 
   System.Web.UI.Page.ProcessRequestMain() +750 

----------------------------------------------------------------------------
---- 
Version Information: Microsoft .NET Framework Version:1.1.4322.2032; ASP.NET
Version:1.1.4322.2032 

The error does not seem to be connected to the web.config, as if the same
error occurs even if web.config is deleted. 

Unfortunately, I have no idea why the error occurs, and couldn't find any
information on this mailling list. 

Thank you for your help!

Best wishes, 
Christoph
