[antlr-interest] Problem finding Template

I'll try this solution. How does the label help here?

I cannot use the pre-beta as it doesn't generate C# code yet (some templates seem to have changed and StringTemplates complains that the C#-template does not match the interface).

But I still don't quite understand: ANTLR tries to load a template which obviously isn't there. So either you have to include that template or you must change the part, which uses the template... Or am I missing something?

Thanks
Hartmut

Hi.  I think ID^^ is the problem, but not sure why... seems it  
doesn't like it for some reason.  Hmm...try 3.0 pre-b6 from site, but  
you can try using a label on any token^^ to avoid I think.
