Unable to bind user to peopleeditor programmatically after SharePoint 2010 August 2011 CU

Question

I have a drop-down selected index change event to set value for a people editor control. This works fine for the first time. But the next time I change a value in the drop-down, the people editor wont change if it already holds  a value. I need
to clear it and then  change the drop-down value,. This issue occurs after August 2011 CU update and does not happen in other environment where i dont have this update applied.
Can someone officially confirm if this a known issue with August 2011 CU? I see this is being reported both in SP2010 and  MOSS 2007 after their respective August 2011 CU updates. Refer

Answer 1

 if (currentUser != null)
//Clear ppl column:: sharepoint ppl id:  peFinanceDepartment
                               peFinanceDepartment.Entities.Clear();
                                PickerEntity UserEntity = new PickerEntity();
                                // CurrentUser is SPUser object
                                UserEntity.DisplayText = currentUser.Name;
                                UserEntity.Key = currentUser.LoginName;
                                System.Collections.ArrayList entityArrayList = new System.Collections.ArrayList();
                                entityArrayList.Add(UserEntity);
                                peFinanceDepartment.UpdateEntities(entityArrayList); 
                                // Add PickerEntity to People Picker control
                                //peFinanceDepartment.Entities.Add(peFinanceDepartment.ValidateEntity(UserEntity));
                                // This should make People Picker control disable|readonly
                                //peFinanceDepartment.ShowButtons = false;
                                //peFinanceDepartment.AllowTypeIn = false;
