Hi Microsoft team,

We have found that State machine workflow in web application (developed on c#/VS 2008 .NET Framework 3.5which "was changing states" not doing so after applying patch Q956802. We are using Windows Server 2003 Standard Edition Service Pack 2 (build 3790),.NET Framework 3.5 and database SQL Server 2005 on a different system. We have tried enabling DTC as well but to no avail. We are using manual scheduler service as well.

Do we have to reset some settings after applying the patch?

Steps to Reproduce
1.Create a statemachine workflow
2.Enable SQL persistence,sql tracking,event services
3.Raise events
4.Query SQL tracking for state using user events like,
public string displayWorkflowsUsingTracking(string WFType, Guid ID)
{
try
{

SqlTrackingQuery sqlTrackingQuery = new SqlTrackingQuery(Connection);

SqlTrackingQueryOptions options = new SqlTrackingQueryOptions();
SqlTrackingWorkflowInstance trackingInstance;
sqlTrackingQuery.TryGetWorkflow(ID, out trackingInstance);
currentState = trackingInstance.UserEvents[trackingInstance.UserEvents.Count - 1].QualifiedName.ToString();
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
return currentState;
}

Actual Results
trackingInstance.UserEvents[trackingInstance.UserEvents.Count - 1].QualifiedName.ToString(); throwing index out of bounds
Expected Results
Current state based on user events

Thank you for your question.

I don't know of anything in Q956802 that would cause this problem.

Can you give us a few more details on the workflow?

What sorts of events are supposed to be causing the workflow to change states?
Where do those events come from?
Is it only one state that is not being tranisitioned out of, or are all states affected?
What exactly did you do to "enable DTC"?
Why did you think "enabling" DTC would solve the problem?
