Login failure: Object reference not set

ajj3085 · Post by **ajj3085** » Thu Mar 20, 2008 8:21 am

Hi,

I installed Vista SP1, and have been getting a lot more of these now. It seems to happen almost every time I start typing to edit a file, which causes an automatic checkout.

I have the lastest version of Fortress client and server.

The exact error I get from the client is: Object reference not set to an instance of an object.

The checkout works, but the file does not have it's Read-only flag cleared, so I have to manually do that.

I'm sorry for the inconvenience. We've had a few intermittent reports of this, but haven't yet isolated a cause. Does it come and go, or are you always seeing it, now that it's happened?

Would you mind turning on diagnostic logging, and sending me a log that includes this error? It if it also included a full Visual Studio startup and opening the solution, that would be helpful. You can attach the log here or email it to ian at sourcegear dot com.

It seems to be everytime now since applying SP1. I'll enable the logging and see if that uncovers anything.

Here's a log; I typed into the file BundleItems.cs, which was not checked out:

Thanks Andy. I have a hunch. Does this file still exist in the repository, at either name?

Code: Select all

$/dotnet/MedQuotes.Business/MedQuotes.Business/Internal/LineItems/BundleSubLineItem.cs
or
$/dotnet/MedQuotes.Business/MedQuotes.Business/Internal/LineItems/BundleSubLineItemNode.cs

ajj3085 · Post by **ajj3085** » Thu Mar 20, 2008 12:38 pm

Yes, as the second name (with Node appended).

In the stand-alone client, in the pending changes pane, does the pending rename of that file appear red, with Namespace Conflict in the Details column?

ajj3085 · Post by **ajj3085** » Thu Mar 20, 2008 1:07 pm

I've seen that before, but I don't believe that file was in a conflict. I did, after posting the log, commit the rename separately (I have a large change set that isn't ready to go yet) and now the error seems to have stopped.

As an aside, what is the resolution to the Namespace conflict? As I said, I've seen it before, but clicking on Resolve did nothing..

ian_sg · Post by **ian_sg** » Thu Mar 20, 2008 1:15 pm

I'm glad to hear the error's gone away.

We have found a case where pended move/renames that have namespace conflicts cause an object reference error. A fix will ship with 1.1.1.

When you right-click a namespace conflict and choose resolve, you should get a dialog giving you the option to un-pend the change or alter its path.
