[antlr-interest] [SPAM] bug? :ActionScript target tree grammar expect <DOWN> or <UP>

[Feng Xiaobo]

hi,I use ANTLRworks create a simple grammar and a simple tree grammer.
When the tree grammer diagram shows <DOWN> blah <UP> the the parser will report expect <DOWN> or <UP> error.
But with the same grammar I change the target to Java it will be ok,so I think this is a bug with the actionscript target.
anyone know this bug? or how to resolve this? ;-(
