Antlr 2.7.7 is just for the StringTemplate stuff, we are actually
using Antlr 3. You could attempt to regenerate the grammar again with
latest versions of antlrworks and antlr, although I'm not sure if it
works without updates to the drl. Not sure when 3.0.6 will be out,
probably not for a few weeks.<br>

antlr that is now
fixed. I'll see if we can get a 3.0.6 release done some time updated to
the
latest antlr. Edson knows more about this, as it was a bug he
investigated.<br>
