[antlr-interest] Why I have to use explicitly $setType()?

[ycmichelid]

My problem (http://groups.yahoo.com/group/antlr-interest/message/5028)
seems to be also a conflict between keyword and identifier.

I found a solution to make my tokens being recognized normally.
I have to explicitly use the function $setType().

In my case , rules in my lexer become (rule to skip whitespace
ignored):

ALERT: "Alert" {$setType(TestTokenTypes.ALERT);};
OPENPAR : "(" {$setType(TestTokenTypes.OPENPAR);};
FUNCNAME : ('A'..'Z')( 'a'..'z' | 'A'..'Z' | '0'..'9' | '_' )+
           {$setType(TestTokenTypes.FUNCNAME);}
;

So, it works now.
But why do i have to set the type of the tokens manually?
