[antlr-interest] Grammar Problem With Custom Nodes

Hello,
This is a small snippet of my grammar:
ident_list : (R0+=ident -> $R0)
( ',' R0+=ident -> ^(TOKN_IDENT_LIST<Ident_List> ident+ )
)* ;
ident : T0=IDENT -> ^( IDENT<VarIdent> ) ;
As you can see, I'm using custom nodes.
For the input "x" I get a VarIdent object. Everything is ok so far.
For the input "x,y,z" I get a <Ident_List> with x,y,z as child's but they do
not belong to VarIdent class as I wanted.
Ident_List(root) -> [CommonTree(x), CommonTree(y)]
How can I tell that the "ident+" should produce a list of idents as childs
of Ident_List instanced as objects of the class VarIdent?
Ident_List(root) -> [VarIdent(x),VarIdent(y)]
thanks,
Miguel
