eventBroker: UI Thread Subscriber doesn't seem to switch to the UI Thread

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Write a subscriber something along the following
[EventSubscription(EventTopics.MyEvent, 
typeof(bbv.Common.EventBroker.Handlers.UserInterface))]
Where you are asking the eventbroker to run in the UI thread

2.
Write an Event publisher that generates the event
[EventPublication(EventTopics.MyEvent)]
        public event EventHandler AnEvent;

What is the expected output? What do you see instead?
The expected is that the delegate will run in the UI thread.. .instead it runs 
in the event broker's thread and causes an exception


What version of the product are you using? 
Current as of 2/27/2011
On what operating system?
Windows XP


Please provide any additional information below.

It appears the method in userinterface.cs below does not do as intended:

Thanks

private Exception CallWithThreadSwitch(Delegate subscriptionHandler, object 
sender, EventArgs e)
        {
            Exception exception = null;

            this.syncContextHolder.SyncContext.Send(
                delegate(object data)
                    {
                        try
                        {
                            ((Delegate)data).DynamicInvoke(sender, e);
                        }
                        catch (TargetInvocationException ex)
                        {
                            exception = ex;
                        }
                    },
                subscriptionHandler);

            return exception;
        }
