Hi all, quick question,
Searching the forums leads me to believe that @synpredgate works at the
rule level. However my attempts (in Java target) still end up with "if (
state.backtracking==0 )" code
Terence posted this, which seems to indicate that it will work

A month earlier he'd described the exact problem I'm facing with syntactic
predicates and setting necessary scope variables in actions during
backtracking. But didn't have a solution at that time.

Thanks
