Object reference not set to an instance of an object.

[chris.bradley]

We'be start intermitantly getting NullReference type exceptions with the VSIP client in Visual Studio 2005. It seems to start happening when the VSIP client tries to "update" the status of all the files in the project. Unfortunately it seems to do it once for each file in the solution and on some of our big solutions it's faster to end-task on visual studio then it is to hit ok to all these messages. I've grabbed some info from the VSIP client log, hopefully this can shed some light on things as it's a very frustrating bug.

Can you close Visual Studio and open your Vault client. Do you have any problems checking out files, editing in notepad (small comment change), and checking the file back in?

Which version of Vault are you on?

[chris.bradley]

I've never had a problem with the Vault Client. It's only inside the IDE that we have issues.

Versions are...
[08/25/2008 2:48:04 PM] Version Check: This Vault client is version 4.1.2.18185
[08/25/2008 2:48:04 PM] Version Check: Your Vault server is version 4.1.2.18185

[Beth]

Do you have Vault open at the same time and/or multiple instances of VS open? If so, can you reproduce it with only having one VS session open and no Vault GUI client?

This is a known issue that's been addressed for Vault 4.1.3, which is not yet released due to server-related testing.

You can download a pre-release version of the 4.1.3 client (which is compatible with any 4.1.x server) here: http://people.sourcegear.com/~ian/Vault ... _18273.msi

(For Fortress users, the Fortress client is here: http://people.sourcegear.com/~ian/Fortr ... _18273.msi).

Thanks Ian - we'll give it a whirl.

Sorry for the inconvenience. Let us know if you have any other problems.
