[stringtemplate-interest] C# indexer - no attribute in template context

[Tomasz Mloduchowski]

Hi!

I'm new to StringTemplate, and I've been trying to use it with an CLR
indexer.

I've boiled down my troubles to this simple program:

using System;
using Antlr3.ST;

public class Lang {
  public string this [ string key ] {
    set {}
    get {return "Foo"; }
  }
}

public class HelloWorld {
  static public void Main (){
    Console.WriteLine("Hi");

    Lang l = new Lang();
    Console.WriteLine(l["XX"]);

    StringTemplate hello = new StringTemplate("Hello, $name$: $lang.XX$");
    hello.SetAttribute("name", "World");
    hello.SetAttribute("lang", l);
    Console.WriteLine(hello.ToString());
  }
}

If I'm reading the documentation located here correctly,
http://www.antlr.org/wiki/display/ST/Expressions

this should just output:

Hi
XX
Hello World: XX


Unfortunately, I'm getting:
Hi
Foo
Class Lang has no such attribute: XX in template context [anonymous]
Hello, World:

Do you have a suggestion? Google reveals nothing relevant.

Cheers,
Tomasz
