Can I declare more than one converter? WP8 - xaml

Question

I am using BooleanToVisibilityConvertor for manipulating visibility of TextBlock in a ListBox DataTemplate.
Here is my XAML code:
<phone:PhoneApplicationPage.Resources>
<Converters:BooleanToVisibilityConvertor x:Key="booleanToVisibilityConvertor"/>
</phone:PhoneApplicationPage.Resources>
<TextBlock Grid.Row="2" HorizontalAlignment="Right" Padding="0,0,7,0" Visibility="{Binding AverageConsumption, Converter={StaticResource booleanToVisibilityConvertor}}">
<Run Text="{Binding AverageConsumption}"/>
<Run Text="l./100 km."/>
</TextBlock>
And the code behind:
public class BooleanToVisibilityConvertor : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
{
if (value != null)
{
if (!string.IsNullOrEmpty(value.ToString()))
{
return Visibility.Visible;
}
}
return Visibility.Collapsed;
}
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
This is working correct, but i need one more (reversed) convertor for another TextBlock placed on the same position (Grid.Row="2" HorizontalAlignment="Right")
with static Text="Partial Refueling" so when {Binding AverageConsumption} is not null or empty first TextBlock will be vissible and second will be collapsed and vice versa. Something like this:
class BooleanToVisibilityConvertorReversed : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
{
if (value != null)
{
if (!string.IsNullOrEmpty(value.ToString()))
{
return Visibility.Collapsed;
}
}
return Visibility.Visible;
}
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
I have tried to declare another convertor in XAML:
<phone:PhoneApplicationPage.Resources>
<Converters:BooleanToVisibilityConvertor x:Key="booleanToVisibilityConvertor"/>
<Converters:BooleanToVisibilityConvertorReversed x:Key="booleanToVisibilityConvertorReversed"/>
</phone:PhoneApplicationPage.Resources>
But got an exception on InitializeComponent():
'A first chance exception of type 'System.Windows.Markup.XamlParseException' occurred in System.Windows.ni.dll'
How can i solve this?

Seems like I've found what is your problem. Your BooleanToVisibilityConvertorReversed class is not public. Make it public and your issues should be gone.
