AW: [antlr-interest] problem with TreeParser grammar -> <AST>:0:0: expecting ), found ', '

[Oliver.Kowalke at infineon.com]

I've tested it with antlr-2.7.4.:
If I parse "otype in ('abc')" it works. 
If I try to parse "otype in ('abc','efg')" I get this error:

<AST>:0:0: expecting ), found ','

It seams that the rule

strlist : LPAREN ( STRING COMMA )* STRING RPAREN;

used in

expression : #(IN OTYPE strlist)

in the tree walker doesn't fit. Why? How to fix?
