[antlr-interest] Syntactic predicates elude me

I am a newbie and for a couple of weeks I've been banging my head on
something simple that I'm just not getting.
I just cannot figure out how to write a syntactic predicate. I'm
testing in ANTLRWorks and I always get an error reported like:
FailedPredicateException(rulename,{synpredN}?).
What puzzles me is that the predicate that is reported is always the
one I expected would succeed based on the input I provide. If I
provide an input that should match (say) the third predicate it will
report the third predicate as the error.
I'm using ANTLR 3.0.1 and ANTLRWorks 1.1.7.
