ComboBoxAdv incorrectly sets new selected value when using databinding. If the old selected value is not the first item in the list and a new value of emptystring is selected the new value will be the first item in the list, empty string is properly selected if the old value was the first item in the list.
Example if selected value is two, select new value of empty, value will be one. In case where old value is one, and select new value of empty new value will be empty.
