has there been any resolution do this issue?

I’ve opened a trouble ticket for this one, as it seems to be a reoccurring issue for me.

Any update on this?  Following an upgrade from 2008 vol. 1 to 2009 vol. 1 (9.1.20091.2087), we began experiencing this issue at random times and only on one development server.  IIS reset always seems to get rid of the error (until next time).  Here is a stack trace:

Stack TraceObject reference not set to an instance of an object.

Object reference not set to an instance of an object. (System.NullReferenceException)

Hi Brian - I've opened a trouble ticket on 9/28 according to Vince's recommendation but haven't heard back yet. My issue seems to be related only to the webdatechooser control. Which makes me think it has something to do with the way that DLL is stored in GAC.  For you it looks like it is the WebDataInput control.  So at least now I know it is not specific to the webdatechooser but probably to do with the way ASP accesses the resource.

I am now investigating whether it has to do with medium trust issues on the server.  Since I can't seem to find an easy way of replicating the error, it is difficult to narrow this down.  I tried using the DLLs in the APTCA and Bin-Signed folders.  When I get a chance, I'll try updating the GAC with the regular DLLs in the BIN folder.

Not sure if anyone knows what are the possible causes for a Null reference at that stage of the page cycle from the stack trace.  Does it mean that ASP can not find the dll in the GAC?   With that, I was thinking of placing all DLLs in the BIN folder and wait and see if the error shows itself again.

Good Luck!

Just checked and a new service pack was released 10/2  version 2122.  The docs does not say whether this was fixed but its worth a try as I'm not sure if this is a server config error or problem with the dll.

I'm experiencing the same issue and just submitted a ticket.  Wow I hope they fix this soon I've had it happen in two different applications now.

Have you resolve this problem ?

I have the same probleme with WebDateChooser et WebTextEdit (Infragistics 2009 Volume 2)

I submit a support request but I did not get response yet.

Rob,

How long does it take for a Infragistics to reply to a support request?

It's not yet certain whether the behavior you've described is caused by the development issue I mentioned before.

I'm having your case assigned now.  To be fair, this will take us time to verify what's happening in your situation.  Thank you for your patience.

Hi Rob,

I haven't seen this issue on our production server since I added the WebDateChooser dll to the GAC.  Mind you it was already in the GAC, but since I was getting this error and on occasion one that says:

System.IO.FileNotFoundException: Could not load file or assembly 'Infragistics2.WebUI.WebDateChooser.v8.3' or one of its dependencies. The system cannot find the file specified.
File name: 'Infragistics2.WebUI.WebDateChooser.v8.3'
   at System.Reflection.Assembly._nLoad(AssemblyName fileName, Str

I decided to add a fresh copy to the GAC in case it got corrupted somehow.

I used the DLL from the "C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 3 CLR 2.0\ASP.NET\Bin"  and not from APTCA or Signed folders.

Running .net 2.0 on win2000 advanced server.

Hope this helps
