[jagsusa]

Hi

In the following code I could trace out the current logged in user but still the control is blank for me any idea ??

  userPicker = new PeopleEditor();
  SPUser user = ipsWeb.CurrentUser;
  PickerEntity entity = new PickerEntity();
  entity.Key = user.LoginName;
 
  System.Collections.ArrayList entityArrayList = new System.Collections.ArrayList();
  entityArrayList.Add(entity);
  userPicker.UpdateEntities(entityArrayList);

even the UpdateEntities is working fine with out any issues but still the control as such is blank

Pls help
