[antlr-interest] Action body losing literal in translation?

[Dejas Ninethousand]

Hi,

I have a production that looks like this:

subtree : descendant_list network_info { stack.pushSubtree(true); }
                  | network_info { stack.pushSubtree(false); };


but when I examine the generate java code the boolean literals seem to be
missing.  Any thoughts on why?

  case 1 :
                    // C:\\Users\\Matt\\Desktop\\ExtendedNewick.g:22:11:
descendant_list network_info
                    {
                    pushFollow(FOLLOW_descendant_list_in_subtree74);
                    descendant_list();

                    state._fsp--;

                    pushFollow(FOLLOW_network_info_in_subtree76);
                    network_info();

                    state._fsp--;

                    * stack.pushSubtree(); *

                    }
                    break;
                case 2 :
                    // C:\\Users\\Matt\\Desktop\\ExtendedNewick.g:23:11:
network_info
                    {
                    pushFollow(FOLLOW_network_info_in_subtree90);
                    network_info();

                    state._fsp--;

                   *  stack.pushSubtree(); *

                    }
                    break;

            }
