New Post: Task History Control Activate Issue

I have a task history control on a form with a task list view. I've included a refresh option on the task list to try and update the task history. When the form first loads and fires the .activate it loads the history just fine. When I call the same method via the refresh menu option it will update the number of events count but does not show the new history in the control.

Here is the code I use

        void ActOnTask(Task t)
        {
            if (t != null)
            {
                currentTask = t;
                currentTaskInterval = t.Definition.Triggers[0].Repetition.Interval.TotalMilliseconds;
                taskHistory.Activate(t);
            }
        }
