MonoTouch.Dialog: Alignment of Text

I am trying to right align the value entered in a cell:

    [Section]
    [Entry ("Nicknam开发者_StackOverflow社区e")]
    [Caption("Nick Name:")]
    [Alignment(UITextAlignment.Right)]
    string NickName;

But Left is used instead of Right? What am I missing?

The Alignment attribute only affects strings, it does not affect Entries.
