[antlr-interest] IllegalArgumentException: Can't find template wildcardTrack.st

[Matthieu Riou]

Hi,

I have a rule in my grammar that must accept pretty much anything inside its
body. The idea is to get that block of code and delegate to some interpreter
external to the main language (allowing the inclusion of Javascript or Ruby
code for example).

The rule is the following (I know, this probably won't work just like this
especially if the function body has curly braces but it's just a start):

function:    'function' f=ID '(' ID? (',' ID)* ')' '{' (.*) '}' ->
^(FUNCTION $f);

Anytime I provide a rewrite rule (whatever it is) I get the following
exception:

error(10):  internal error:

Any idea?
