I have more information about the problem now:

If I do not have an identifier rule and if I have keywords in the
grammar then the problem I explained in my previous mail (below) occurs
(and this is normal I think). If I have include the indentifier rule in
the lexer and if I do the testLiterals stuff and when I try to test the
parser it just HANGS without any messages.

Now, is there any suggestions?
