[antlr-interest] NoViableAltException in argumentList

[Lucas Ontivero]

Hi all,Somebody could help me with this? I have the following rule: argumentList    : argument (',' argument)* -> ^(ARGUMENT_LIST argument+)    ; argument    : typeName IDENTIFIER -> ^(ARGUMENT typeName IDENTIFIER)    ; typeName    : 'char'    | 'bool'    | 'int'    ; And when I use the interpreter of AntlrWork with:int a, bool b AntlrWork  shows me:


argumentList 

argument 

typeName 

int 
a 
, 
argument 

typeName 

bool 
b 
NoViableAltException Why is that exception? Thanx all.
