RadComboBoxEditor items with value of NULL is not persisted to bound object model.
I'm binding a list of objects to the grid that allows edits. The column is bound to a property of type Object. One of the items in the combo box has a value of NULL (representing no selection). Selecting this item does not update the underlying bound object.
side note: change the item's value to DBNull and binding works as expected. This provides a work around, but forces undesired knowledge of DBNull in the bound presentation model.
