[Prados Valiente Enrique]

Thanks, it's right.

Any sample of Lexer, Parser and Tree grammar ??

> I try generate tree grammar, and I get this error:

I believe that your problem is that you *don't* have a tree grammar. 
Instead, what you have a is a combined grammar (Lexer and Parser).
Remove the word "tree" from the line which contains "tree grammar" and 
see if that fixes your problem.
