Set SelectedItem in RadAutoCompleteBox

[Adam]

Hi,
I need use RadAutoCompleteBox instead DataFormComboBoxField which works perfectly.
Problem is when I start editing. In ComboBox selectedItem is showing but in AutoCompleteBox is blank space.
works:

<telerik:DataFormComboBoxField
                                ItemsSource="{Binding DataView, ElementName=UmowyDataSource}"
                                DataMemberBinding="{Binding UmowaId,Mode=TwoWay}"
                                DisplayMemberPath="NumerUmowy"
                                SelectedValuePath="Identyfikator"
                                Label="Umowa"
                                />

not works corectly:

<telerik:RadAutoCompleteBox ItemsSource="{Binding DataView, ElementName=UmowyDataSource}"
                                                            DisplayMemberPath="NumerUmowy"
                                                            SelectionMode="Single"
                                                            Name="Umowa"
                                                            SelectedItem="{Binding Path=UmowaId,Mode=TwoWay,Converter={StaticResource ProjektyStatusConverter}}"
                                                            TextSearchMode="Contains"
                                                            TextSearchPath="NumerUmowy"
                                                            />

Also
Convert:

public class ProjektyStatusConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            if (value != null)
            {
                return value;
            }
            else
            {
                return value;
            }
        }
        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {

            if (value != null)
            {
                UmowyItem umowa = value as UmowyItem;
                Int32 umowaID = umowa.Identyfikator;
                return umowaID;
            }
            else
            {
                return value;
            }
        }
    }
