Vault Client 4.0.1 (15780) on Windows XP

I am trying to check in files using the Vault UI. I had an entire project checked out and tried to checkin the entire project.
If I check in parts of the project - a few files at a time I am successful.

I tried the same operation on a Win2003 and Vista works fine.

I have tried uninstalling and reinstalling Vault.

Vault worked fine before I upgraded the last time.

Thanks,

Tom,

Can you enable IDE logging and post the relevant log section when you're getting this error?

I too have this issue. When checking out or GetLatest.

AutoDesk Vault has even released an hotfix...

We use version 4.0.2 (15802)
Here is the log:

This is only a part of the log. I can't post more because of our own security policy.

Thanks.

I found the problem. I had multiple pending "Rename" actions. This behaviour is a little weird.

I did rename some directory some time ago and they are correctly renamed. But I still have a Pending action to resolve in my list, which does nothing when I try to resolve it. I must undo the action in the pending list (mouse right click) to remove it, but the rename is still effective.

I suggest changing the user message in the MessageBox to guide a little the user about how to resolve that type of problem.
