I am not so sure that manually building a tree that would work with listeners/visitors generated from a second grammar is going to be an option. I have asked on SO and on the Antlr discussion group and basically got no responses as to how that might be possible. See https://groups.google.com/forum/#!topic/antlr-discussion/vBkwCovqHcI
So the question is whether generating a semantic tree that is not Antlr specific is a viable alternative. I think it is. And we can still provide hand written listener and or visitor for processing this. _______________________________________________ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
