Well I am not sure I understand your meaning sorry. When the selectedObject instance on the model has a date member variable that is blank, the field starts blank, but once the the field changes, but not the instance, that text never leaves the date field. It does it however when I use text or label boxes that have null string member variables. So I dont understand why the date field is working so differently.
