Could you sent me the code generated for the rules ? I'm not 100% sure if
it's a bug or not. Also do you have a dump of the real structure of the AST
that went wrong?
I know that for myself working with antlr treeparsers generated quite a lot
of 'oh duh!' moments, when something turned out to be slightly different as
expected, but quite logical in retrospective.
Not sure if this is such a case. My first impression is at least that it
should work. Did you check with -traceTreeparser that the right alternative
was chosen?
Cheers,
Ric
