ComboBox Binding is lost when bound item is swapped for a new item containing null for the field



Category : Operating Systems

I have a "User" screen where a User entity is bound. When it starts off as a new user, the values bound to the combobox is null so the combobox starts off blank and the works as intended. If I then click my "New User" button, any comboboxes that were switched from the empty null value to a value while still on the previous entity seems to completely lose their binding on the new User. Any comboboxes that were left initially Null before clicking "new" continue to operate correctly. After this my combobox is completely dead. Changing it's value will not make it's way back the the source, and when loading a new source the combobox is no longer selecting the right data.
