[antlr-interest] Lexer rule precedence

[Massimiliano Donini]

  Hi, i have one problems on lexer rules and i can't understand why.
As attachment  there's a piece of my grammar where i got the error:
Debugging i can correctly match 'NULL', but i can't match 'DEFAULT NULL' 
there something that i miss....
I think there is something wrong with lexer rule precedence, but not sure.
Any help would be really appreciated

Greetings Max
