Wrong Text on SelectItem

[Oleg Gochachko]

<telerik:RadComboBox
            Grid.Column="0"
            ItemsSource="{Binding Path=DropDownCollectionView}"
            IsSynchronizedWithCurrentItem="True"
            DisplayMemberPath="Code" IsEditable="True"
            EmptyText="Code"
            SelectedItem="{Binding Path=Container.Data, Mode=TwoWay}"
            Width="75" VerticalAlignment="Top">
    <i:Interaction.Behaviors>
        <wpf:RadComboBoxClearTextOnLostFocusWhenSelectedItemIsNull />
    </i:Interaction.Behaviors>
</telerik:RadComboBox>

 

For some reason after set Container.Data ComboBox Text has Object.ToString() value rather than the Object.Code property value however items of combobox dispay proper values.

public TData Data
{
    get { return _data; }
    set
    {
        if (_data == value) return;
        _data = value;
        RaisePropertyChanged();
    }
}

public TContainer Container
{
    get { return _container; }
    private set
    {
        if (_container == value) return;
        _container = value;
        RaisePropertyChanged();
    }
}

DropDownCollectionView is ListCollectionView

And this strange bug happens only if ListCollectionView.Filter is present even if filter result is always true ( "return true;" )
